*THE* Gen 5 Glock thread: First Impressions, Reviews and Thoughts

[RJ]

Rich,

I would buy one of everything since Glock parts are cheap. Take advantage of the platform and have a generous spare parts kit.

5000 rounds is nothing. If something is amiss in the gun, send it to GI for inspection and overhaul.

I asked @Pensfan what the parts replacement schedule was for Gen5 guns. He said that he replaces the recoil spring in his personal gun every 10k rounds. He didn’t mention any other parts swapping. I couldn’t hurt to swap out your recoil spring if you’re worried about wear on the gun but it doesn’t sound like you need to prioritize any other small parts this early.

Thanks guys. Sounds like I can keep buying ammo.

-I had a rough trigger mechanism housing, a polymer part. The polymer where the trigger bar's "cruciform" rode was rough and only replacement of that part cured the problem. This was on a G21SF.

Yep, the trigger mechanism housing is sometimes the unidentified culprit in sub-par Glock triggers. One of my two gen 4 G19s had a rougher trigger than the other. After much diagnosis I narrowed it down to the slot in the trigger mechanism housing that the connector flexes back into -- it was just *slightly* too tight. A few passes with a file, removing an imperceptible amount of polymer, smoothed it out nicely.

Another approach is to have some Glock parts in duplicate or triplicate and switch them around until you get the trigger feel you like.

Lately, I am convinced that for competition, I shoot a Gen 4 34 better than a G5. Not sure whether it is the finger grooves or something about the different trigger, but the timer consistently favors G4 by a small but measurable amount.

I feel if the finger grooves fit well, they really work well.

That’s how Bob Vogel does his triggers. He just has multiples of the same connector and maybe other parts and plays around with it until he finds a combo he likes.

Yep, that's what I normally do, but it didn't help this one.. I have a fairly ridiculous stock of duplicate Glock internals.

I’ve been running nothing but a G17.5 and G17.4 for the past six months. The G5’s grip and trigger “feel” better but I’m noticing the same thing you are. The G4 that (for me) “feels” tougher to shoot well is actually giving me better times and scores. Can’t explain it. I was prepared to not like it as much as the G5 but I can’t ignore what the timer and targets are telling me. Both have Dot connectors and the only changes I’ve made are better sights.

For the sake of science, could you swap recoil springs and see what happens?

No can do, i’m afraid. The G5’s RSA does not interchange with the G4’s and I tend to steer clear of non-OEM parts on Glocks save for sights.

Are the sights the same basic design on the Gen 4 and Gen 5? Meaning are they both using fiber optic or night sights and are the front post and rear notch comparable.

Wasn't there a change in sight heights between the two generations? Have the makers (including Glock) sorted this out completely?
