Another 4,000 rounds have sailed down the pipe since the last update with very little to report, really.

10-8triggerI’m definitely liking the 10-8 flat trigger. Other than sights and mag catch, the new trigger was the first real change I’ve made to the gun. The overtravel adjustment is probably too generous and unlike most screw-in overtravel stops the 10-8 trigger uses a fixed/filed stop so there’s no going back. I actually like the 10-8 approach better — the overtravel screw on my original trigger backed out this past May — and I’m sure I’ll pick up another to try again sooner or later. In the meantime, the overtravel and reset is still far less than you’d get on most non-1911 pistols so it’s difficult to complain too loudly.

Accuracy continues to be decent even with a third of my rifling gone. Earlier this week I was hitting a 3×5 on demand at 25yd off hand. The pistol definitely had more performance to deliver, but 25yd is about the limit of my vision trying to hit a grey card on an off-white background at an indoor range.

Two major changes to the gun for the coming weeks:

two-slidestopsI’ve replaced the slide stop with a Wilson Bulletproof, pictured to the right (Wilson part on top, stock Springfield part on bottom). The original stock part has a steep sloping thumb catch while the Wilson part has two ergonomic advantages given how I run the gun.

I use my support hand thumb to drop the slide on a 1911 because I cannot reach it with my strong (right) thumb. One of the issues I discovered as my reloads slowly improved was that my thumb sometimes slid off the angled contact point on the stock slide stop without releasing the slide. The thumb shelf on the Wilson part is level so it serves as a better “hook” when hitting it fast during a slidelock reload.

Second, because the shelf is thinner from top to bottom it allows a marginally higher grip without interfering with reliable slidelock. At least, that’s the theory. We’ll see how it runs.

The other change? Wilson sent me one of their flat wire recoil springs. While Wilson recently made a big splash with heir new HD/+P 8rd magazine incorporating a flat wire spring, they have been offering a flat wire recoil spring for a while. While nominally designed for .45, the spring functions in the 9mm gun as-is… though slide speed is noticeably retarded. Based on recommendations from people who’ve use the Wilson flat wire in 9mm pistols before, I’ll probably cut a couple of coils. The flat wire spring has ten times the service life of a a regular spring. So when this gun hits 100,000 rounds I may need to get a new one.

My schedule should allow for a fair bit of shooting over the next couple of weeks. Check back for the next update!

  2. Did you have to do anything to fit the trigger and slide stop?

  3. Todd: I can see the 9mm. Or the flat trigger. But do you find folks giving you an odd look when they discover that you have both?

    By SteveJ on Oct 12, 2013

  4. MT — The 10-8 trigger required minor fitting plus filing the overtravel stop; both requirements are mentioned on the manufacturer’s web page and were expected. I haven’t done any live fire with the Wilson Bulletproof slide stop yet so I don’t know if any fitting will be necessary. It works fine in the gun when I hand cycle.

    Steve — Huh?

  5. Other than the overtravel, what else is rings positive/negative about the flat v. curved trigger face. Just curious about any tactual differences that have caused you to make adjustments.

  6. Todd –

    … though slide speed is noticeably retarded.

    Do you mean the slide is taking longer to cycle, or just that its velocity during cycling is reduced? Or, is it just that the spring is doing a better job of controlling ramp up / ramp down on slide velocity?

  7. Todd: In response to your “huh?” my comment was nothing but innuendo–although apparently totally unintelligible innuendo.

    By the way, staying on a 3X5 card at 25 yards is really nice for a tactical pistol. Can you do that with range ammo or is that only with your +P HST?

  8. Good news from an obvious ,shooter …many never condsider 5,000 rds.of shooting muchless 50,000.
