CE325 Posted February 26, 2017 Share Posted February 26, 2017 I recently disassembled my G17 and polished the trigger etc. took it to a match today and when I pulled the trigger it fired 1 round then quickly another. It happened 2 times and I noticed when pulling the trigger and holding it then racking the slide the slide does not fully return. Here is a video anyone know what's going on??

Edge40 Posted February 27, 2017 Share Posted February 27, 2017 That looks like a recoil spring. That is actually glocks test for the recoil spring. Hold the trigger down and rack the slide easing it forward. That doesnt explain the burst mode though. Is it always only 2 rounds or does it sometime go more than that?

pskys2 Posted February 27, 2017 Share Posted February 27, 2017 You have a mismatch between the recoil spring and the striker spring. Try a heavier recoil spring first. Link to comment Share on other sites More sharing options...
CE325 Posted February 27, 2017 Author Share Posted February 27, 2017 It only fired one extra round 2 times. After that it has worked fine. But it doesn't seem normal Link to comment Share on other sites More sharing options...
EliColotta Posted February 27, 2017 Share Posted February 27, 2017 OP, why don't you tell us all the mods you done on the pistol and save us some time in trouble shooting it. It's doubtful that the doubling is being caused by polishing. What parts did you change and what springs are in the pistol. Link to comment Share on other sites More sharing options...
CE325 Posted February 27, 2017 Author Share Posted February 27, 2017 I installed a 3.5lb connector in it and extended slide release, mag release in it about 5 years ago. Recoil spring is stock along with everything else. It has around 6-8k rounds fired and about the same dry fired. Link to comment Share on other sites More sharing options...
Edge40 Posted February 27, 2017 Share Posted February 27, 2017 Glock factory 3.5lb connector or after market? Link to comment Share on other sites More sharing options...
CE325 Posted February 27, 2017 Author Share Posted February 27, 2017 After market. Link to comment Share on other sites More sharing options...
Edge40 Posted February 27, 2017 Share Posted February 27, 2017 Which after market connector is it. Some of them aren't drop in. They require some adjusting. Link to comment Share on other sites More sharing options...
CE325 Posted February 27, 2017 Author Share Posted February 27, 2017 I think lone wolf. But like I said it was years ago and it has been working fine. Until I recently polished and cleaned/lubed it. When the slide is back you can see the trigger bar lift up through the gap between the slide and frame. Idk if that is normal or not never noticed it Link to comment Share on other sites More sharing options...
Captains1911 Posted February 27, 2017 Share Posted February 27, 2017 (edited) Have you ever replaced the recoil spring? If not, it is overdo because the recommended life is 3k-5k rounds. That should fix the issue of the slide not going into battery as seen in the video. As for the doubling, you mentioned that it started after polishing parts. Exactly what parts, and what method did you use for polishing? Edited February 27, 2017 by Captains1911 Link to comment Share on other sites More sharing options...
Edge40 Posted February 27, 2017 Share Posted February 27, 2017 I'm thinking the slide not going into battery and the bursts are separate issues. I would change your recoil spring and see if that solves the not going into battery problem. After that I would check the engagement of the trigger bar crucifix and the firing pin. Glock makes a special slide plate that allows you to see that engagement. If the crucifix doesn't engage the firing pin enough the firing pin could slip off and cause another round to go bang. A new trigger bar isn't very expensive and sounds like good insurance to avoid full auto by accident. Link to comment Share on other sites More sharing options...

I used a Dremal with a little polish compound. Nothing crazy. Link to comment Share on other sites More sharing options...

Probly will replace the trigger bar also. Link to comment Share on other sites More sharing options...

darkvibe Posted February 28, 2017 Share Posted February 28, 2017 Make sure the spring under the firing pin stop plunger is in right. Probably jammed in the hole sideways. Link to comment Share on other sites More sharing options...

akaider Posted March 2, 2017 Share Posted March 2, 2017 Best bet would be disassembling the gun and reasembling (everything). That way you can inspect any parts that may be holding the gun back. If theres actually a part with an issue you should see a mark somewhere, specially if you are letting the slide slam on it with a fair amount of force. Btw how does the guide rod and spring feel when installed to the barrel? Does it hold with a fair amount of force or does it come off easily? That should give you a ball park if you need one or not.

CE325 Posted March 10, 2017 Author Share Posted March 10, 2017 It's been set aside for now. I got a new stock 2 I'm going to be using for now. I will figure it out when I get back from vacation Link to comment Share on other sites More sharing options...

Probably jammed in the hole sideways. ^^^^ This. Same thing happened to me a few years ago, turns the gun in a auto-doubletap machine. Pretty scary actually; and very easy to do if your not paying attention to the FPS spring as it goes in. The extra hang-up to the trigger bar is what makes it "catch" before returning completely into battery. I actually had several Glock armorers look at it, and they could'nt find the problem.
