Glock 17 gen4 Endurance Test: Week 19

0 malfunctions 0 parts breakages

Nothing particularly exciting to report about the test gun this week. I pulled the trigger a bunch and it went bang every time.

The Trijicon HD sights evaluation continues. They’re not perfect, but they do all the important things very well. In fact, they’re so easy to see on high-prob targets at speed that I found myself getting lazy with sight tracking lately. It’s just very natural to get into an intermediate distance focus and press the trigger whenever the orange blob is aligned on the target. For finer work they’re a bit less forgiving but still more than adequate. For example, I decided to see how far out I could consistently score three hits on an 8″ from concealment in 2 seconds. I was 100% at 12yd and about 90% at 15yd. When I slow down and take my time, keeping shots inside a 2″ at 15yd is definitely possible.

I also spent some time playing with the upcoming 5 Shot Leather appendix carry holster, which looks promising. There are still a few tweaks to be incorporated but after more than a year and a half we’re definitely on the home stretch. When it becomes available, it will be introduced at pistol-forum.com with quite a bit of fanfare I imagine.

The backup G17 got another 100 rounds of practice ammo this week and has begun ejecting erratically. Brass goes anywhere from straight right to over my left shoulder. It hasn’t had any stoppages but I’m more inclined to push the gun to 2,000 now to see if it will develop the same problem as the test gun.

Next week will be a fairly light shooting schedule. “The Nation’s Gunshow” is in town and historically that means twelve billion untrained first time gun owners will descend on the NRA Range this weekend, Monday, and Wednesday night (the first evening the range is open after the show). Rather than fight the crowds and count how many muzzles get pointed at me, I’ll probably just spend some dedicated time with the SIRT training gun and then get in a live session on Friday.

Train hard & stay safe! ToddG

  2. Todd;
    Good choice re the “muzzle counting”!!!!!

  3. Todd,
    It is funny that you mention the erratic ejecting. I also have a Gen4 G17 that still has the factory extractor with about 5K rounds. I was at the range today shooting and noticed a few pieces of brass actually came back and hit me in the chest when normally the ejection path is to the right and forward. I found it weird but did not think much about it till I saw your post.

  4. A back up? LOL Still had to change parts to make it function properly….Garbage….I’ll stick with HK

  5. Any chance on some Trijicon HD sights for the HK P30?

  6. Can you provide pictures of the breech face and locking block?

  7. Think the Trijicons will hold up to rust well? My other aftermarket Glock sights are all rusting.

  8. rob_s: The most honest answer I can give you is that I don’t know. Sights, like many small parts coming from outside vendors, tend to have variations in finish that can lead to bad batches. Historically I’ve seen this less often with Trijicon but I’m sure there will be people who can show you pictures of their rusted-out Trijicon nightsights.

  9. I don’t know if this has been raised before. Apologies in advance if it has.

    You ought to consider filing off that bump/ dent on the trigger bar, the one at the ramp that deactivates the striker drop safety. Some people claim that doing so reduces and smooths trigger pull and helps slide function.

  10. J — While I don’t disagree, that is more modification than I’m willing to do on the test gun. If there were malfunctions afterwards or worse (like the trigger bar breaking), everyone would assume, fairly, that the filing on the trigger bar could have contributed.

    And to be honest, I’m hard pressed to complain about the trigger with the “dot” connector installed.

    By ToddG on Aug 5, 2011

  11. Your point makes sense. Thanks for responding.

    The only thing I’d add is that Gen4 owners should be aware that their trigger bar may now be designed to ride against their slide (unlike earlier Gens). This could potentially affect trigger feel and slide function. Since you’re doing a long term test, you may want to look at the wear in that area.
