AustinMike Posted May 27, 2009 Share Posted May 27, 2009 I've got a relatively new G34 (maybe 500 rounds through it) and I polished up the internals. It's completely stock except that I put a factory 5# connector in place of the 3.5# to try. I like the crisper break of the 5# connector and wanted to give it a go after polishing - yeah, so I'm weird like that. While function testing, I discovered that if I held the muzzle up with the slide vertical and then drew back and slowly eased the slide forward with the trigger held back, it would stop short of full battery lockup. Tipping the slide back horizontal or releasing the trigger would snap it back. I disassembled the gun again to make sure I didn't get anything in wrong and polished up the firing pin safety and the part of the trigger bar that presses it, figuring that's where the problem probably is given that it closes when the trigger is released. I also wiped the slide glide I had on the rails off and used oil instead. It's better now and I can only get it to do it every so often. It's so close I can practically breath on the slide to get it closed completely. I've only got a couple G17s to compare to and they snap right closed. I'd say the barrel fit is tighter on the newer G34 though. Anything to worry about? If so, what else should I check? Link to comment Share on other sites More sharing options...
Rising Sight Posted May 27, 2009 Share Posted May 27, 2009 Are you sure it has a stock recoil spring? Link to comment Share on other sites More sharing options...
AustinMike Posted May 27, 2009 Author Share Posted May 27, 2009 Are you sure it has a stock recoil spring? Yep. Bought the gun brand new last year and just got around to messing with it. All that has changed is grip tape, sights, and swapping the connector out for the 5# Glock connector. Link to comment Share on other sites More sharing options...
SA Friday Posted May 27, 2009 Share Posted May 27, 2009 You are probably getting some resistance from basic friction around the barrel, chamber, and ejection port. 500 rounds isn't enough to break in all the machining, parkerizing, coating, etc. Try it again in 2500 rounds. It should be smoothed out by then. Link to comment Share on other sites More sharing options...
AustinMike Posted May 27, 2009 Author Share Posted May 27, 2009 That's what I was hoping. This is my first "virgin" Glock. My G17's were refurbs or police trade-ins - so loose they just about rattle, but shoot fine. Link to comment Share on other sites More sharing options...
VegasOPM Posted May 27, 2009 Share Posted May 27, 2009 Put some lube on the rails and shoot it. The question is, does it go into lockup under spring pressure? If so, you are fine. Link to comment Share on other sites More sharing options...
AustinMike Posted May 27, 2009 Author Share Posted May 27, 2009 Put some lube on the rails and shoot it. The question is, does it go into lockup under spring pressure? If so, you are fine. It appears to be now. At first, it would stop just short of lockup when the slide was vertical and stay there until tipped horizontal or the trigger was released. Since fiddling with it some more and applying oil in place of the slide guide it's better. The room temperature grease may have been just enough to slow the lockup. I'll go shoot it some more. It's probably just that I'm just not used to having a new Glock that locks up tight. My others looked like they lived hard lives before I got them.

Maybe you got a bad recoil spring from the factory. Link to comment Share on other sites More sharing options...
dirty whiteboy Posted May 27, 2009 Share Posted May 27, 2009 shoot it some more. If you need some extra factory springs let me know, I have a some you can have. (springs without the guide rod) Link to comment Share on other sites More sharing options...
gunnerBU Posted May 27, 2009 Share Posted May 27, 2009 Mike, I had the same thing happen to my G34 about 500 rounds in. The only thing I could do to get it to function properly was to lube up the barrel. No problems since then. Link to comment Share on other sites More sharing options...
LPatterson Posted May 28, 2009 Share Posted May 28, 2009 I thought the test was to let the slide go forward naturally, then tilt to vertical and pull the trigger to make sure the recoil spring was holding the gun in battery. I'm learning something new every day but then the G24C is only a week old and #6 for GSSF. Link to comment Share on other sites More sharing options...
