Glock Locking Block Pin Walk

[AugustoRenguero]

Hi everyone! Im Augusto and Im from Argentina, finally got my first hard earned Glock two monts ago, its a gen 3 glock 23. Great gun, and im loving it, but the other day i made a detailed disassembly and cleaning because here ammo its way too expensive and the only realistic way to somehow shoot frecuently its reloading, thing is the guns got very dirty very soon and because its my carry piece i though that a gun deep clean would be a good idea. I watched a youtube video on how to remove the frame pins (left to right) so i did it(no hammers) just a small pin pusher. But the guy reasseble it left to right, not right to left how its supossed to. I did that way, and rappidly disassembly it again and put the pins in the right way making sure that the locking block pin got perfectly centered. Then i went to the range and shoot 80 rounds with no problem, yesterday i went again and shoot 100 rounds rappid fire because i dedicated my session to practice some bill drill skills. Thing is that when i got home and i inspected the pins, the firing block pin moved slighty to the right, it didnt protude from the frame, not even close. But it certanly moved to the right a little bit. I centered again but im afraid that in the middle of a match it will come loose. Or im just being paranoid? Here there is no glock certifed armorer or glock warranty. Plus spare OEM parts are really hard to find. I read every post on the topic and some solutions include: not big deal, centered again/replacing the pins for new ones/put some nail polish/ put some super glue.
I found a local company who makes glock parts, and bought a pair of new stainless steel anti walk pins. But knowing how things are made here, im a little reductant to replace OEM parts. What do you guys think should i do?
Thanks in advance, love the forum and sorry for my english

I have been a Glock certified armorer for nearly 30 years and have only seen pins walk out enough to be a potential problem on some very used/worn first generation guns that were used/abused in the armorer's course. The pin can move side to side a little, but I've not seen any issues on any guns that were actually in service. I've seen far more serious wear issues take the guns out of service and the pins were still doing fine. Others experience may differ.

Thank very much for the replay! So its normal a little side to side movement, im in peace now. I though that it will be some how accumulative. So eventualy the pin will walk out or i would need to be recentering the pin often.
As a former glock armorer with experience, what do you think of these local made pins that i purchase just in case. Ive notice that they dont have the dumbell form like the OEMs they are straight and have the anti walk cut. This somehow could be potentially harmful for the gun?

I have never used aftermarket pins in a Glock. No specific reason. Just never had a need or want to do so. Some folks say that those pins do not flex with the frame and can enlarge the holes, but I am skeptical of those claims. The design with the anti walk cut should be good. As long as they are sized properly for the frame holes and made of the correct material for strength I think they will work fine. If I were designing a pin like that I would use a "U" shaped cut instead of a square bottom cut. Sharp inside corners are prime points for cracks to form if the part is under stress. I cannot tell the details of the pins from the photo.
