wtf mate

i've been having the same issue. A fresh mag will pft around 15 times until some of the internal pressure is released. I have the enhanced recoil spring from guarder installed and has been installed for a long time. The gun has been working flawlessly for months but the other night i did some fine sanding on the rails and around the hammer assembly. just to remove some of the paint and create a smoother surface for less friction. Ever since, it seems the hammer isn't moving as smooth, almost like it is rubbing. I took it apart completely thinking that maybe some of the fine metal filings got gonked up with the lubrication and was creating unwanted friction. But once put back together the same thing was happening. Thinking there might be a correlation between the minor filing or "sanding" is creating the issue, i've gone ahead and ordered some new hammer assembly parts in case this is what's causing problems. I find it very hard to believe that this is what's causing the issue though, as i took only enough of the metal off to remove the paint, and not heavily, you can still see there was paint but it's smoother, the amount of metal taken off is in micro-meters, barely detectable. I truly think that there is something happening with the hammer and the firing pin's relationship. Maybe it's just the hammer spring, i should try putting the stock spring back in, i hear the new glocks are stocked with stronger springs capable of withstanding green gas.

I am really curious if ap27 got his issue all figured out. It seems cellulose had the right idea, but has yet to respond with any insight regarding his focus on the parts he filed.

also i should mention that when cocking the gun, all the internals move and function properly. hammer is locked, sear is tripped trigger is rest. It's only when gas is introduced that there is mechanical issue. fuck!
