Anyone Ever Had One of Your Assembly Pins Come Partially Out at the Range?
Here’s what happened, in order:
- Purchased a 21lb recoil spring for my Gen 4 GLOCK 27 (if you don’t know already, that’s a .40 S&W)
- While waiting on order, sent e-mail to support to ask them if it was ok to use with factory ammo
- Receive spring in mail & install it (on package the spring was in, it simply said that it was to reduce recoil, and didn’t say anything at all about what sort of ammo to use with such a spring).
- Receive eMail from Glockstore support saying that it was intended for +P ammo, and that I might get some “stove pipe jams” using “regular” factory ammo. No mention of any other possible issues.
- Went to range. Fired about 120 rounds.
- Came home, happy that it had worked well with factory ammo. Recoil/muzzle jump reduced & accuracy improved a good bit.
- Field stripped the pistol to clean it, and discovered my rear (through the grips) assembly pin was halfway out
- Pushed pin back in with my thumb
- Put my +P self-defense ammo magazine back in & re-holsterd for concealed carry, & haven’t shot it since.
Now, I have sent the Glockstore an email asking if that spring could have attributed to the pin coming partially out, and told them I was extremely glad it didn’t come totally out while I was shooting. Sent that mail this morning and an awaiting a reply.
Meanwhile, I’ve ordered some stainless steel replacement assembly pins, and a Glock armorer’s tool (& a 3.5 lb trigger connector).
Now I’ve been considering that pin coming partially out a good bit. Doesn’t make sense to me at all. I don’t care if the recoil spring was 31 lbs, that should NOT have happened in my opinion. The very worst thing that should’ve happened would be a “stove pipe jam” from the slide not cycling rearward far enough to allow for proper case ejection. There is no way that I can think of to justify my pin coming half out. It just DOES NOT MAKE SENSE TO ME!
So, anyone ever had anything similar happen? If so, did you determine why?
If you haven’t ever had a pin come partially out during a shooting session, given the above info, do you have any speculations as to why MINE did?
It just couldn’t be internal pressure from factory ammo that did it. The spring would merely compensate for increased pressure. NO excessive pressure should have been put upon the grip area, especially by factory ammo, UNLESS the slide was cycling rearward too hard and in turn hitting the rear of the pistol wayyy too hard on the forward motion. However, if it had been doing that, then certainly I would have gotten a jam because the slide would have cycled forward so dang fast that a casing would have not properly ejected. Also, forward slide pressure against the frame on the return stroke seems like it would do nothing causing a lateral motion necessary for the pin to slide out at all. Actually, to me it seems like it would just draw the pin into the frame harder, rather than loosening anything up.
ANY IDEAS ON THIS WHOLE PIN ISSUE??? If it happened to you, what would you do? Think my pistol is FUBAR?
I suppose I’ll contact my armorer and ask them for the time being, but I just can’t imagine they’ll say anything more than to put the factory spring back in, which I do NOT want to do. I bought the dang thing to reduce recoil, and it does so even with factory ammo which was still properly extracted. See, I only have my 2nd, 3rd, little finger & thumb on my shooting hand. I lost my index finger & metacarpal due to a severe thermal burn when I was working on an ejection seat in the USAF…which is a lot of the reason why I NEED to reduce recoil. I can get a good grip on the pistol, even one handed, but after 100+ rounds, the ‘regular’ recoil starts to wear on my hand to the extent that the hand slides upward on the rear of the frame (slightly above the “beavertail” and I sometimes get just a little slide burn on the web space between my (now) first finger & thumb…hence my intense desire to reduce recoil.
Does anyone think there might be a manufacturing defect in my pistol? Would you call GLOCK? I may. I just don’t friggin like the idea of taking a chance on my pistol coming apart on me while firing a round. That just could not possibly be a good thing!!!! I mean, I don’t think it would “blow up” in my hand — heck, with the other two pins still in, I doubt much of anything would happen — but regardless, a pin coming part way out during a range session is definitely an issue as I see it.
I’ll take whatever input anyone may have on this. Be sure to consider the facts I’ve given and run the logic on the concept, but comment away if you would? 😀
