      Exactly what I thought also, slide milled with an elevation cant.
      I have a Thompson/Center T/CR 22 with a 20moa tilt in its 1911 rail, I ran out of elevation in the optic I installed. Used Burris Pro rings to reverse the cant and get my elevation adjustment back.

    Good morning HR. I had the same problem with a Holosun 507 on my Masada. It zeroed with the red dot maxed out on elevation. But the suppressor height iron sights also hit low. I have to split the white dot on the front with the top of the rear sight to hit point of aim. Maybe a couple of whacks with a big hammer would settle the sight lower on the slide.😂

    Sir, here is the issue and how it is corrected. Manufacturers and machine shops not familiar with optics on a 1911/2011 only learn this after it is learned the hard way. Me included when hard fitting optics to 1911's. In the 1911 platform the barrel is in the slide at an angle. It is higher at the barrel hood than the muzzle. It is simply the way a 1911 locks up. Some are higher in the hood than others which gives the barrel a slight angle downward from rear of barrel to muzzle.
    Most machinist will index the cut level with the top of the slide. This makes the plain of sight in the optic barrel with the slide not the barrel. And angle finder has to be used on the actual barrel hood to fin d the difference in the angle of the slide and barrel nested in the slide when locked up. Once this angle id found, add two to 3 more degrees to the cut which will give more adjustment to the optic for longer ranges is desired. ;

Since these pistols have only been out for a few weeks, I suspect we will see this corrected in future production runs.

    I believe I can see that the elevation of the milling is different front to back on the Tisas. If you eyeball the top of the slide serrations with the bottom of the milled channel, you can see it. Just a few thousands of an inch will make a big difference at 25 yds. Looks like you have a fix for it, but Tisas needs to address this if there is a milling error.

    I'm pleased that you've gotten your Tisas sighted in to your satisfaction. Almost two years ago I purchased a Tisas US Army "Blem" for $329. I sent it to Green Tick Tactical Solutions and they cut the slide specifically for a Holosun 507K optic and Ceracoated the slide for $165 total. It has worked perfectly with plenty of elevation adjustment remaining at 25 yards so I suspect, as you do, that the cut on your slide is slightly off. I also have several Cyelee optics including a Cat Pro 6 moa green dot that I mounted on my Canik CM9 and I've been very pleased with all of them. IMO and experience, Cyelee makes a very good optic at reasonable prices.

I was able to keep them all in the -0 area of an IDPA target but had to aim just a bit high for it to hit a 1" dot.

    Just looking at the cut on the slide it seems to be higher in the front. You can measure from the top of the slide at the front of the cut and then at the back of the cut. I can see it on the amount
    of radius difference on the side of the slide.

  • @funkla65

    How tall is the rear sight relative to the front? Ideally, for the optic sight to be relatively centered in its adjustment range, the slope of the optics cut should run about parallel with the slope of the iron sights.
    Barrels in tilting barrel guns can be quite a bit out of parallel with the slide. In my Tanfoglio Witnesses, the barrel is nearly flat when unlocked, and sloped downward markedly when in battery.

    My 5" Tisas DS couldn't zero a Riton MPRD 2 red dot. Same issue as you - POI is lower than POA, and the optic ran out of elevation before it could zero.
    On the fairly-low-volume Tisas subreddit, there have been a handful number of reports about inability to zero red dots due to elevation issues. Same issue - the optic cut is too high at the front.
    There are plastic shims for exactly this purpose on Amazon ("red dot plastic shim"). I made a thin shim out of electrical tape - 6 layers was just right to allow my optic to zero on my pistol.

    I have the duty size Tisas DS and with the iron sights. it's quite accurate out of the box. Looking at your video, it does appear the distance from the edge of the cut to the top of the serrations is greater at the front than at the rear. I wonder if shimming the rear of the Holosun with some thin cardboard or plastic would solve the issue ? I have encountered the "shooting low" problem with a couple of my pistols with iron "combat sights." In one case, installing a higher rear sight solved the issue. In the other, the rear sight is part of the optics cut cover plate, so changing the rear sight is not possible. When I tried to zero an optic, I encountered the same issue where I could not bring the red dot down far enough to achieve zero. I did not pursue the issue to the point of trying an optic with a greater adjustment range. I brought this to the attention of the importer (not SDS) and they were not particularly receptive to my observation. The problem was limited to just one variation of the pistol where the rear iron sight is part of the cover plate. I am of the opinion certain guns are just set up such that they shoot low and in shooting, the front sight must be raised to the point where it is just above level with the rear sight. This is why I maintain the firearms industry needs some sort of standards for how pistols are designed to shoot.

    Fine sir, I hope to pick your brain a bit. I am 55 years old and been using iron sites on pistols since I joined the USN at 18. I’m recently getting into red dots and want your opinion on sighting them in.
    I zeroed at 50 feet using a Caldwell pistol rest. All seemed well until I stood up and assumed my normal shooting stance. Suddenly all my groups were several inches high and to the left.
    In your opinion should I examine what the variance is in my stance or how I grip or hold the handgun versus using the rest or should I have sighted it in from my standing stance?

    • @hrfunk
      @hrfunk  10 месяцев назад +1

      ​@@bripro68 That is what I suspected. Here's what I think might be happening. When you shoot from the rest, you are either consciously or unconsciously applying downward pressure on the front of the pistol. Essentially, you are holding the dust cover/rail tightly down against the rest. That probably gives you a nice steady sight picture, but it reduces the normal muzzle flip you would experience under recoil. When you shoot from a standing position, there is no way to do that. Consequently, the muzzle rises more while the bullet is traveling through it. The net result is that the bullets strike higher on the target. The fact that you're hitting slightly to the left probably occurs for much the same reason, except the factor causing that to occur is the torque applied to the pistol as a result of the rifling twist. This is why, when I shoot from a rest, I only allow the rear portion of the grip to contact my sandbag. The pistol then recoils more similarly to the way it does when I'm standing/unsupported.

      At this point, I’m fairly certain that there’s a problem with the slide. Even so, I’m not too concerned about it since I was able to adjust the Cyelee light to compensate for it. At some point in the future, I might contact SDS to see about replacing the slide, but I don’t see that as being urgent.

    Hey! Cyelee site says 30 minutes of adjustment, but does that mean total from the lowest possible to the highest possible or from the center to the highest AND from the center to the lowest? Also, something seems odd that a sight with a published 30 minutes of adjustment could move the poi 50+ minutes..That first shot with the Cyelee looked about 14 inches low...25 yards...Distance from the bench measured perfectly? With you, I'd think so...Uneeda pair of bino's to see those shots!!! :-) Hmmm..I'd simply get a stainless steel shim kit and cut/drill it to fit over the rear screw holes on the slide and go from there!! Might help!! I enjoy your videos

    • @hrfunk
      @hrfunk  10 месяцев назад +1

      Thank you! Usually, the total movement for sight adjustment is measured from the very bottom to the very top, and all the way from one side to the other. When the sight is mechanically centered, you have one-half of that total adjustment range available in any direction. Most sights, and this is certainly true for the Cyelee, have a greater adjustment range than they advertise. Regarding the 40 MOA of advertised adjustment, I KNOW I read that, but I now can't find it on the Cyelee website. In fact, I can't find any stated adjustment range for the Cat X Pro. Since I was able to zero the Carry Ds at 25 yards (with elevation to spare), the Cat X Pro definitely has more elevation adjustment than the Holosun 507K, but unfortunately, I can't direct you to a specific citation for the advertised maximum adjustment range.

  • @MBZ-Nation
    @MBZ-Nation 10 месяцев назад

    Having a good chunk of experiencing building my own 1911s, my own analysis is that this is definitely due to an "issue" with the slide cut. I have issue in quotes because it's hard to cut a slide on a mass-produced gun without it having matching issues between slide angle or barrel angle, especially 1911s that have locking barrels that tilt ever so slightly. I have a couple of Holosun 407c&k and 507c&k and a few Riton sights. It's worth mentioning that Tisas DID show off their new DS line with a Riton sight, and also did advertise those sights. This isn't my first gun to have reflex sight adjustment issues,. However, the level that the cut is off is a bit ridiculous in my opinion. Adjustments should only be needed on a sight to adjust for barrel to slide angle differences, not because the slide cut is totally off. This reeks of poor quality in my opinion, even though I really do like this DS. Also, this is a 100% issue due to slide cut. The front is cut higher than the rear. This is obvious if you measure from the top of sight to bottom of slide. The front cut area measures greater than the rear, and it actually fights against the barrels angle. 1911s traditionally have a barrel that ever so slightly angles downwards inside the slide once locked into place. The cut on this DS is angles upwards. Two apposing angles will undoubtedly cause adjustment issues.
    There are 3 ways to correct this. From cheapest to most expensive(depending on smith availability):
    1. Add an angled shim.
    2. Recut the sight cut.
    3. Refit a new barrel bushing so barrel locks at a slightly higher angle.
    Since I have a 3d printer, I opted to 3d print my own shims. Has been working perfectly fine since.
    This is also one reason why I prefer 1911s with bull barrels- they alleviate a lot of these barrel-to-slide-to-sight cut problems.

  • @Paladin1873
    @Paladin1873 10 месяцев назад

    It's probably a trick of the camera, but to me the optic's cut does not look parallel with the slide. One way to find out is to take the necessary precise measurements using either a dial or digital caliper. Place one jaw of the caliper against the top front of the mounting plate and the other jaw against the bottom of the slide. Check your reading. Now repeat this procedure at the rear of the slide, then move to the opposite side of the slide and repeat the process. The four measurements should all be identical. When measuring, make sure your caliper is always square with the slide and not tilting fore, aft, or sideways.

    Whatever the problem is, I was still disappointed on the groups you shot. I think that you should be shooting slightly tighter and more consistent groups with this pistol & an optic. Maybe prove me wrong but shooting another pistol & optic inconsistently. I agree, this most likely is a problem with the machining of the slide cut for mounting the optic. But if an optic has the ability to adjust for 40 minutes of angle, that would typically be 20 up and 20 down, not 40 up. Thanks for the video. Even though I am not satisfied with the results, I like watching how you work your way through a shooting problem.

    I'd like to add a DS 1911 to my collection at some point without breaking the bank, so I'll be keeping my eye on this one. What worries me as much as the (possibly) bad optics cut is that your group size seems so large considering you're shooting stabilized with a dot a 25 yds. Based on other videos of you as a shooter, I would blame the gun for that, not the shooter.

    HRF, sorry you had a lackluster experience with this pistol. The concept is well thought out, but the execution not so much. I'm addition to the optic mount issue, the accessory rail on the carry model is too short to accommodate many common weapon lights like the X300, TLR-1, TLR-7, etc. (The 5" model can fit those lights, though). The MAC9 DS (also by Tisas/SDS) seems to be a much better pistol for not much more money.

    The slide cut is not parallel to the bore. In all probability, the slide was not fixtured correctly before being milled. This is not fixable. The slide is scrap. Tisas should replace the slide assembly. I have no doubt that slides are inspected on an AQL sample basis. Your slide likely never had any more than a visual inspection after finishing.

      @hrfunk Absolutely. I have had an issue with Girsan 1911. It shot very low. Fortunately, the rear sight is adjustable for elevation and windage. However, I had to use most of that adjustment. I found my local gun shop had two of the same 1911 in stock. I showed up with my digital calipers and measured the height of the front sights. That on my pistol was .020 taller than the other two... Being a dove tail sight, I simply replaced it via the aftermarket. Seemed like a faster solution than sending back to EAA for repair. I would have replaced it anyway. The pistol is optic ready, but the rear sight is on the slide cover. So, I would lose the rear sight. I did install a Burris FastFire3 for a while. However, I elected to revert to the irons. That FastFire3 is now on an 870 pump shotgun. In this application, it excels.

I get that it’s a “budget” pistol but I would rather spend a little more for better performance. Perhaps a Springfield Prodigy. I personally wouldn’t pick a Cylee over a Holosun for any rifle or pistol. This could be a QC issue with an early production pistol as you say.
