150 more rounds of 124 grain AE and 50 rounds of 147 grain HST. Lots of FAST drills and some timed 6-plate rack, so plenty of opportunities for reloads. No feeding or extraction issues. There were 3 instances where the slide dropped when an empty mag was ejected and 1 instance of failure of the slide to lock back on an empty mag. 2 of the instances of the slide dropping occurred with Wilson Vickers mags; the other with a Tripp Cobra. I do not recall what mag was involved in the failure to lock back. All of these slide issues occurred during timed drills.
It’s not uncommon for me to have my support hand muck with the side stop lever. The slide dropping with mag release is fairly uncommon for me though. I inspected the lever and there is no abnormal wear. The mags did not appear to be dirty or weak sprung. So, it’s very possible that it was my support hand getting a little sloppy.
Still, I’m encouraged by the results so far. I’m coming up on 500 rounds with no major feeding or extraction issues despite introducing some JHP ammo to the diet.
