Glock frame flex on trigger pull

[MikeRush]

I have a Gen 2 police trade in G17 that I have been using for production (and sometimes limited). I have been trying to get the trigger pull to be more smooth and predictable, and with stock springs and a dot connector I am happy with the break. However as I go to take up the slack the trigger bar causes the right sight of the frame to perceptibly shift outward. I had tried tweaking the old bar to minimize it, and I just threw in a new bar and its a bit better, but it is still somewhat disconcerting that every time I squeeze that trigger I have to overcome the resistance of the frame.

Is this a design feature? The interior of the frame seems to have cutouts designed to wipe the trigger bar clean. Can I do something to add a bit more clearance or is that how it is supposed to be? I haven't noticed other glocks being like that. I will compare it to the G24 I am picking up on Tuesday.

The frame is flexing visibly outwards? Can't say that I've ever seen that happen. Can you post a video?

I never knew about it, but my 35 does that. I see it spring back inward after the striker drops.

Yes it is flexing visibly outwards, video isn't coming out because nothing I have will do macro video well. I can actually feel it swell in my strong hand up until the striker releases, at which point it springs back in as a.roberts noted. I am tempted to get out the heat gun and a plywood wedge, but that seems maybe too risky. I guess it isn't critical, but it would be nice to not have to be flexing my frame as part of my trigger pull.

Have you contacted Glock?

This sounds like a good idea, give them a call & let them know of the issue, some posts have mentioned that they will probably have you send it to them & they may just replace the frame & other parts, if I remember correctly they would replace a frame for less than $50.

If you wait for your G24, you could have something to use in the meantime if you decide to send the G17 in. They'll probably give you a Gen 3 frame with the same serial # as the one you currently have unless you're specifically looking to keep the Gen 2 style.

I have not contacted Glock, I suppose I could do so but I have no interest in a Gen 3 frame, and I suppose that is no guarantee either that my next one will not flex. I go out of my way to find Gen 2 frames because I don't particularly care for the Gen 3 "enhancements".

I figure if guys do grip reductions and stippling and all that (tame compared to some of the mods I have seen guys do) a heat gun shouldn't scare me. Just finished, sighting along the frame reveals a straighter line on the outside than when I got the pistol. Feels good, didn't make a huge difference, but took out some of the increased pull before the break and made me feel better. I think perhaps my trigger bar has too much lateral movement (and I have tried several bars), I am not sure what is "normal" but I think my issue is fixed now.

Update: My Gen 2 G24 also has some trigger bar induced frame movement. However I cannot feel it while gripping the pistol normally, and it is very slight. I will just leave that one alone. Trigger doesnt have the same staging issue my 17 had.
