I cleaned & lubed my GEN4 G19 on November 23, 2022. I always check things over while cleaning. Look for damage, make sure safeties work and test the RSA.
Everything was normal.
Yesterday I pulled the 15 round mag out and inserted a 33 round mag - gun has not been fired since cleaning.
I rack the slide as I normally do - gave it a pretty good yank and did not ride it - and the round went straight into the feed ramp and did not load.
So I dropped the mag - gave it a few taps - made sure the top round was loaded correctly and reinserted it -
This time I racked it really hard - and I made sure 100% I did not touch the slide but let it slam forward - and the round nose dived into the feed ramp and did not load.
I dropped the mag again - unloaded it and reloaded it (not sure why I thought that was a good idea) and reinserted it and racked it like I stole it -
The round went straight into the feed ramp and would not load.
At this point I was baffled - so I dropped the 33 round mag - locked the slide back and inserted a 15 round mag and then dropped the slide using the slide stop and it loaded the round no problem.
I then tried the 33 round mag and it loaded no problem - did this a few times.
I them - starting with a fully loaded 33 round mag - inserted the mag and slowly pulled back the slide and allowed the slide to slowly go forward - trying to make it fail -
But no matter how easy I released the slide - even holding it back so it would slowly move forward, it still loads a round every time with no failure.
I did the RSA test a few times and no matter how hard I try to get it to fail the RSA seems GTG.
This is a fairly new 33 round mag - it has only gone to the range 1 or 2 times and has been left loaded for over a year. The spring seems strong as the last round is hard to load. I do not think the mag spring is bad.
I am thinking about calling in the expert!
