Good comparison with some good pictures. They say the guns are very similar, and, echoing a lot of YouTube reviews, they say the P365’s recoil is a bit more mild (they do add that they’re “grasping at straws,” and that the guns are more similar than anything). https://www.thetruthaboutguns.com/heads-up-sig-p365-vs-springfield-hellcat/ Cliffsnote: Pro Hellcat- holds 1 more round, and is optic ready. Pro P365- mild recoil, slightly thinner throughout, better slide serrations. From the top of the slide to the bottom of the trigger guard, the P365 is “shorter” than the Hellcat, so the position of the trigger is more forward and higher, as well as being more “undercut” for the lack of a better term.
