Couple ideas for further enhancements. You can bend the rails of the slide where they interface with the tabs of the frame when the slide is in battery in order to take out the play and provide more consistent trigger feel and barrel lockup. I've also read about people tac welding a few spots on their barrel where it protrudes through the slide at the muzzle end and then hand filing them down to get perfect lock up there as well. Couple things I'd like to try eventually but haven't gotten around to it.
Huh I havent really heard of people doing that on striker fired guns. Lots on 1911s and stuff. coincidentally I am working on tightening slide to frame fit on a 1911 right now.
@@EngineersArmory But why? Does it sound like maracas? Slide to barrel would be nice, like a ring bushing or the 'magic' H&K O-Ring would be cool and make a biiig difference.
@@onpsxmember my MAC9 sounds like a maraca yes haha. The slide to frame fit is awful. The fit of the barrel hood in the slide, upper lug engagement, lower lug, barrel link length are all good. Front of bull barrel is a little loose in the slide but not terrible. Its accurate enough for my purposes.
@@onpsxmember I like the idea of the O-ring from a service weapon perspective. It can have looser tolerances when cycling for reliability and margin for environmental conditions and how dirty the gun might be. But then tighter clearances at lockup for accuracy. I have an HK45 with that o-ring. It's an awesome shooter.
Wow there buddy 😂. Great video as always. PP Port 🍆. I wouldn’t worry the carbide job will smooth out over time so even if it’s rough now it will be less so after a while. For people doing stippling or carbide I’d recommend grabbing one of those A2 grips they probably have laying around and practice on those.
Haha thanks man! Yeah I've noticed the texture has gotten a little less rough. Some of the chunks that were barely hanging on to the epoxy thru the cracks of other pieces have come off. After some use it may end up about perfect with another few hundred rounds.
I think this turned out pretty good. Those Brownell's slides were pretty meh from the start of their production. I heard a lot of issues back in 2019-2021 about undersized parts, and you ran into it with yours. Obviously a little undersized FPB hole ain't gonna stop you, or your PP(orting). I like the dick porting. Yeah, it's impractical due to the size, but you're the first person to do porting in the shape of the frank and beans, and I think there's some merit there. If I still had a Walther PP, I'd think about PP porting that. Then I'd have a double PP. PP squared? Thanks for the upload! I always enjoy the videos!
Not all PP times are PooPoo times...but all PooPoo times are PP times. The spalling issue, is this due to the "shaft" port snags the projectile as it exits the barrel? And is there a way to counter bore a relief on the ID of the ports to prevent this spalling?
The wider the slot, and the longer it is (the shaft in this case), the more likely the bullet will come apart. Its very difficult to create inside chamfers and radii, especially in a hole or slot this small. I dont have that capability. That probably would help. But i think the biggest part of it is that the bullet is under a tremendous amount of pressure from the rear, and also the rifling. The bullet is the same diameter as the grooves. The rifling lands squish into it to create the gas seal. A lot of bullets are open to the lead core on the back now, The copper jacket doesn't completely encase the bullet. Those are more likely to come apart as well. As a general rule now (which i broke these rules with this porting job so it looks SUPER cool), I dont make holes larger than 7/64" (.109"), and i dont make slots wider than 3/32" (.094"). I take the spalling more seriously now not only because I have seen how it tears up barrels and slides, but some spalling fucked me up. I had to get two 3-4mm long pieces of lead surgically removed from my noggin. At some point i plan on synthesizing everything I have learned about porting into one video. i still have some more testing I want to do before then. But ive ported like... 12 pistols now? Ive learned a lot.
Love the PP Port. Keeps the Pis(s)tol on target.
Great data; also agree that 71Creative kit is amazing.

Can it work with any barrel? Edge prep, material would be a cool project how different pistol sizes can benefit or not.
I kind of want to do this with my G17L but I got the ridiculously long comp to make it even longer so maybe I'll go with a G34 instead!
The G34 with the comp is pretty close to 17L length as far as I can tell.
Excellent. I love my gen 5, G34. It's my duty and carry gun.
Needs a pecker in the barrel👌🏼
@@EngineersArmory The pecker is the ultimate "fu@k you", LOL... I wish I live in US.

I would love to see the PP porting catch on. I could redesign it to reduce spalling and jacket separation.
@@EngineersArmory I just may need to send you a barrel and slide in the future...
@Paul_Whaley but only if it's a PP port😂
@ That’s the only porting I’d want ❤️❤️❤️
@Paul_Whaley my man🙌🏻 figured so hahhaa. Only real riderz get the PP port.

How much?
Um, not a good look.
I think it is.🤷♂ Its silly.
I don't know how that is possible. Looking forward to the next video though.
