Honkeymcgee Posted December 20, 2017 Author Share Posted December 20, 2017 Here's a short video of the ejection. Don't mind the Gucci Voss waters, it's a joke with a shooting buddy of mine. ? https://youtu.be/mBnzhJ5BHfQ Link to comment Share on other sites More sharing options...
Honkeymcgee Posted December 20, 2017 Author Share Posted December 20, 2017 Hoping to get a test for done in the next day or two. Comp will be here Thursday and hopefully I can get all my slide cutting done this weekend. After that I'll just be waiting on an optic mount I'm buying from a friend.

Honkeymcgee Posted December 22, 2017 Author Share Posted December 22, 2017 (edited) Got a little more work done and took it out for a test fire today. Comp is on and timed, tritop is done, and dust cover is cut back. Ran into some light primer strikes and feeding issues during the test run. Not sure what caused the feeding problems as all my dummy rounds were cycling fine. Smoothed up some areas that may have been problematic so hopefully that issue is fixed. Have not been able diagnose the firing pin issue yet. With the barrel out, holding the slide in place and watching the firing pin hole I can see that some trigger pulls result in a good strike of the firing pin while others I can't see the firing pin pop out at all. I can't detect that the hammer is slowing down at all and with the firing pin spring out the firing pin falls freely so I am really at a los on this at the moment. Any way, here's a few pics and videos. Edited December 22, 2017 by Honkeymcgee Link to comment Share on other sites More sharing options...

Broncman Posted December 22, 2017 Share Posted December 22, 2017 What firing pin are you using? I had to go to an extended firing pin and have had no issues since. And of course, make sure there is no drag on firing pin stop or in firing pin hole in breech face. Link to comment Share on other sites More sharing options...
theWacoKid Posted December 22, 2017 Share Posted December 22, 2017 (edited) Looks good. Make sure you are getting full square contact from the hammer on the firing pin. What length is the gun? Edited December 22, 2017 by theWacoKid Link to comment Share on other sites More sharing options...
Honkeymcgee Posted December 22, 2017 Author Share Posted December 22, 2017 Well I think I got it narrowed down a heavy duty firing pin spring that I ordered not thinking about it. Cut a few coils off and it improved the failure rate but still had some. I cut a few more off today and will check again tomorrow. Hangups I figured out today we're from the reverse plug contacting the comp on the way back into battery. Put a chamfer on the reverse plug so that should be taken care of as well. Will update after a range session tomorrow. Link to comment Share on other sites More sharing options...

Broncman Posted December 22, 2017 Share Posted December 22, 2017 Glad you got it figured out! I used a ball end mill and clearances the bottom of my comp similar to how an STI DVC is. Basically a round Grove for the reverse plug. I also chamfered the plug as well. Link to comment Share on other sites More sharing options...

The comp had that but I had to extend it farther and it was already thin where it came clearanced from Atlas so I turned down the part that is exposed a little bit in the lathe to clearance it.

So with the KKM commander I think you're at the 4.1" shorty size. I like it. Now get to hacking some material off that slide! Link to comment Share on other sites More sharing options...

I have to figure out how I'm going to do my slide cuts because the mill I have been using doesn't have a swivel base that I can set an angle on easily Link to comment Share on other sites More sharing options...

Basically all I do for rotating around the z-axis. For cuts angled about the x and y axis I mostly use tapered end mills. I also see you have the slide jig. For my rear swoop cut I just used that to hold the slide at 90 degrees and side milled it with a large diameter cutter.

Broncman Posted December 23, 2017 Share Posted December 23, 2017 (edited) Angles are easy! Get on Amazon and for 39 bucks get a set of angle plates. They come in a set from 1 degree on up. Then take a universal indicator attached to the quil/spindle and you can indicate your vise in any angle you want. Just use the surface of the angle plate clamped in your vise to get the right angles on the vise. You can also use the angle plates to set the angle of your slide or jig in your mill vise. Will take a pic tomorrow and show how I did it. Edited December 23, 2017 by Broncman Link to comment Share on other sites More sharing options...
Honkeymcgee Posted December 23, 2017 Author Share Posted December 23, 2017 Awesome, appreciate the info guys. Waco, that's exactly what I planned to do for the rear cut. Largest good mill I have right now is 1/2", which is what I planned on using. Link to comment Share on other sites More sharing options...
yigal Posted December 23, 2017 Share Posted December 23, 2017 awesome ! did u cut mag release cut by mill or file it by hand? Link to comment Share on other sites More sharing options...

Put a little extra relief in it since the pic so it doesn't bind up during firing. Link to comment Share on other sites More sharing options...
Honkeymcgee Posted December 24, 2017 Author Share Posted December 24, 2017 Well the firing pin issue is not solved yet. Today I ordered a couple more mainsprings, a Dawson hyperdrive firing pin, and a new firing pin spring. Will see if any of that helps. Here is a pic of what primers are looking like currently. Any ideas would be greatly appreciated. Link to comment Share on other sites More sharing options...
Nugget Posted December 24, 2017 Share Posted December 24, 2017 Did you use go/ no go gauges when you finish reamed the chamber? Are the primers sticking out of the cases further after firing ( primers backing out)? Are you using full house loads? Link to comment Share on other sites More sharing options...
Broncman Posted December 24, 2017 Share Posted December 24, 2017 The Dawson extended will take care of that. Exactly what mine looked like before installing an extended pin. For some reason the extended pin cuts back on primer flow. What load are you using? Link to comment Share on other sites More sharing options...
