In fact, they didn't teach us much of anything other than how to strip and reassemble, ad nauseum. Oh yes, the lunch was complemented by a huge, day-long dose of Glock Kool Aid. But as far as what to do when this or that happens, there simply wasn't time to cover it. Probably in the "Trouble-shooting" level course, eh?

So anyway, I detail strip my Gen 4 G19 for the fourth or fifth time since I bought it new. All cleaned up and reassembled, I didn't like the feel of the striker safety/extractor retaining button. (technical terms) I go to put the slide on and it stops hard about 1/10 of an inch from all the way on. Natch, I suspect the safety and sure enough, there was the spring lying sidewise in the channel. Needle nose pliers to the rescue and one new spring later, I figure I'm good to go. Well, the slide stops in exactly the same spot. Hmmmm....starting to get tense, hereabouts.

I pull the slide forward, make sure the RSA is in its proper place and try again. No luck. I move the trigger bar back and forth just a small bit to see if anything is binding. I try again and voila! It slides right on and works perfectly. (so far as I know, haven't had it to the range yet) It does have the new RSA from Glock in it, fwiw.

I know, without a doubt, that within the collective knowledge of the members of this exalted board that there lies the perfectly logical reason that my slide would not slide fully on the frame. Any and all ideas are welcome, since at this point I'm just as clueless as I was before it went together. I'm the type of guy that doesn't want to just know that it works; I want to know WHY it works. And/or why it did not. I'm sure many of you are the same.

Anyway, thanks in advance and sorry for the wordy post.

What?

I don't know exactly why it happens, I suspect that the arm of the trigger bar that engages the firing pin safety is slipping off to the side of the safety and getting stuck.

The solution is to do one or both of these:
1. Before putting the slide back on the frame, hold the slide muzzle toward the ground and press the firing pin safety into the slide, then release the firing pin safety. Doing this will allow the firing pin to drop past the firing pin safety and will hold the firing pin safety in its depressed position.
2. Before putting the slide back on the frame, put your thumb on the back of the arm of the trigger bar that engages the firing pin safety and push that arm forward toward the muzzle. This will put the trigger in the forward position so that the arm is lower when you reassemble the gun and the arm won't get stuck on the firing pin safety.

Some people had to to one or the other, some people had to do both. Some people report that after a while there's no need to do either. :dunno: Some recent production Gen3's and Gen4's do it, but not all. One of the Glock Armorers at Show Show 2011 showed it in one of nutnfancy's videos. Here's the video, at 11:04 into the video he talks about pushing the trigger bar forward to reassemble the gun.

If moving your trigger bar back and forth allowed you to get the slide on, you may have an issue with the trigger, engagement "bump" on the bar (which, I beleive all Generation 4's now have), or the crusaform may be out of spec, too high perhaps? Anyway, replace the trigger/trigger bar and see if that solves the problem. As an armorer, I keep spare parts around for just such situations. Then I take the gun to the range, swap out parts until I get to the offending party and away they go!

I thought it was a given that the striker needed to be in the fired position before reassembly of the slide to the frame.

Thanks GT!

When you are installing the spring into the firing pin safety plunger, make sure you are pushing the spring in until it clicks into place and locks there.

Follow Voyager's advice in solution #1. Do not pull the trigger forward as it puts unnecessary pressures on the cruciform and trigger housing when the FP lug has to press the cruciform down into the housing while it is sitting on the higher level of the drop safety.

Thanks, Voyager for that video. I didn't realize it was that common of a problem. And thanks, TX for the idea of swapping trigger bars. Hopefully one fix or the other will do the trick.

Oh, I just got back from the range and the Gen 4 G19 with Glock's newly-issued RSA works beautifully. It chucks WWB to the right just as hard and consistently as it does Winchester NATO ammo. Very pleased with that aspect of the whole ordeal.

And thanks again, guys.

I had the same problem with my Gen4 G22 or G23 (don't remember which). My problem occurred after only field stripping it. I found the same solution you did.

My slide can be put back on the frame with the striker in the fired position, or with it sucked back in the channel liner, either way, never really makes much of a difference on my gun.

Did you leave/take your mag out?

Did you leave/take your mag out?

I guess somebody had to ask and you are somebody, right?
Good thought, though. Yeah, it was out from the get-go. Not that I haven't ripped the slide off one before with a mag inserted. But, no, this was a detail strip. I took out essentially every part of the gun save the mag release and the "takedown bar," more properly called the slide lock.

 

[HandyRake]

Lol, nothin against you! Just gotta check every angle! Had a buddy do that a while back.

Really, ripping the slide off with the mag inserted. That is pretty stupid. (I've done the same thing.) :embarassed::embarassed::embarassed:

Not everyone is gonna admit it, but we have all probably done it a time or two to one gun or another. Glocks aren't the only offenders.

What did you expect them to tout, the 1911? :upeyes: :supergrin:
