I just shot the P938. The recoil is actually quite mild (to my much surprise). Mechanical accuracy is also quite good.
However, there are many reports of reliability issues with both hollowpoints and ball ammo, so take it for what it's worth.
I assisted a lady with only 50-rds of ball ammo to shoot through her gun and there was one failure of slide not lock back on the last round. I believe that it is shooter error (limp wrist). I didn't have any issue with it not locking back or short cycling when I shot it. This lady is still a novice.
As far as the safety lever goes, it's a non-issue if the owner were to invest the time to practice with it until handling had became second nature. This applies to all guns, of course.
Can you dig it?
