Questions regarding my 20sf issue

[RMM]

Brian... I am late to this party.  What trigger bar do you have in the gun (does it have the "bumped" striker safety interface?)

My Gen 3 G20SF also started doing exactly what you are describing, it would run fine then lock open with one round left in the magazine.  I thought it was my grip but after some testing I figured out that is wasn't.  Then I went to magazines, I tried four different ones with the same result.  I then removed the slide lock and bent the spring so it had more tension, but at the same time I replaced the trigger bar with a new bumped one after I had screwed up the old one.  It stopped doing it but I'm not sure if it was bending the spring or replacing the trigger bar that did it.  Just some thoughts.

Rmm its the bumped one.    I am looking to go shooting this coming week so with all the things I did I hope it runs right..


But will see

It's got my curiosity.  Hope all ends up solved.  Looking forward to the range report.

Not sure what exactly is going on with the slide locking open on the last round and it not being resolved with new parts, but this sounds like the slide stop for sure. Also, the slide stop has the spring crimped to it, so I'm unsure which two individual parts were being installed previously. I have a feeling the slide lock and spring were installed and not a slide stop. As for the trigger bar with the bump, that's was only to align the bar correctly under the firing pin stop.

I have this slide stop installed on my Glock 20 GEN4 and have zero issues.

I did put a new solide stop and slide lock spring but have not been shooting with all the new parts installed.  Been busy with family matters as of late.   But I will post when I get out to shoot again.


Thanks for the info. 


And a big welcome to the forum
