I really like the rear sight. I’ve been running fiber optic front sights for years although green works better for me. The work you did on the grips is great. The hammer Bob and trigger re-shaping also look good. For anyone thinking about going inside a Smith & Wesson revolver, get Kuhnhausen’s book. Follow that - not all of us experts on the internet. My guess is that this presenter knows exactly what he’s doing, but his general comments could lead someone into real trouble. Please do *NOT* advise people to “remove the machining marks” inside. Most of those areas don’t actually touch anything; however, there are areas that bear upon the hammer, trigger, or other internal parts. Smoothing off machining marks inside can make things really sloppy inside - things that should not be sloppy. If you run the gun for 500 rounds, you will be able to see where parts are rubbing. Might not even take that many. Polish those spots only. Do not remove metal. If the hammer or trigger are scraping on one side, check for side-to-side play. A shim on the side that’s rubbing might give just enough clearance to stop the interference. Don’t touch the trigger or hammer engagement surfaces unless you are trained to do that work. Ditto for the hand. (I am not.) The bottom and sides of the rebound slide can and should be polished. The place on the frame under the rebound slide also should be polished. Using a Cratex rod, you can polish inside the tunnel where the rebound spring rides.
I agree. If you are a first timer to tuning revolvers...and maybe you are only planning on tuning one or two revolvers it's much easier, and possibly less expensive, to give it to a gunsmith. If you are a DIY'er, and want to do it yourself, then start slow. Just do some spring swapping first. Then check for function. Then try another LITTLE thing. Then check for function. The key is little at a time and always check for function between changes. ALSO, ammo...specifically primers... is very important for revo reliability. So always use the same ammo/primers you intend to use for competition in your tests! Thanks @chipsterb for your advice to the audience!
Where I live, the stores are smaller and handling a firearm before purchase is a luxury I haven't had in over 10 years. I justorder them, wait a ridiculous amount of time(not always) and take it home. Fortunately,I haven't found a gun that was so repulsive when it finally arrived that have not needed to refuse purchase. Obviously, I am not talking about consignment guns.
Great video. I’m considering a 929 for steel challenge and found this information to be very valuable. I’m also curious on which size Dawson front sight you went with. Please let us know, if you get a chance. Thanks.
I still have it and shoot it occasionally. The biggest challenge is keeping it clean or using a load so it makes enough gas. So a good gun for a reloader, but not so good for off the shelf ammo. The DI 45 seems to be much better in that regard. I may give the DI 9mm another run with some modifications that I thought of after this prototype.

I went with this one .215" Tall x .100" Wide Ramped Serrated
should have for SURE taken the side plate OFF so we can see insides
what became of your AR15 Prototype 9mm DI?

Would have been much more helpful if actually took it apart and did the modifications on video
