I always manage to circle back around to Glocks for the most part. A buddy had purchased both the Sig and the Springfield. He didn‘t care for Glocks all that much and tended to find fault in just about any subcompact pistol. I fired his Hellcat and it shot okay - can’t think of anything that really stood out. I didn’t get to fire the 365, but personally loved the trigger and ergonomics - and size. He noted that he has had problems with the 365, Hellcat and G43x in that his hands were large and he kept riding his thumb on top of the slide stop lever preventing the slide locking back on an empty mag (I have medium hands and had the same problem with the Hellcat). Nevertheles, it concerned him enough to get rid of all three of those guns. Based on my observstions, the 365 may be the easiest to conceal of the three, but its also a relatively moot point between a 365, Hellcat and original 43. Between the Sig and Springfield, I’d pick the Sig, but it’s really about the individual shooter‘s preferences and performance.
