So I had heard of needing the two stage spring replaced with a single stage recoil spring due to failure to extract. Well, I’m doing the break in and it loves the 147 gr HST (not +p), the spent casings landed in the next zip code.
The 100 gr critical defense lite and 124 critical duty would get hung up like a double feed with the empty.
Interesting on the flip side is the 43x with a tango down extended slide lock would lock back in the middle of a mag when shooting the 147 gr. The first two I assumed it must have been me sweeping it up somehow but the third I kept my right thumb on the outside of my left thumb knuckle so it seems it would be an quirk of the platform or the aftermarket slide lock.
