Have just over 300 rounds through my 365. I had Two issues with the slide not locking back on last round that was the first 150 rounds approximately nothing since. With the slide lock back inserting a full magazine and sending it home the slide Went to into battery, that happened four times. Compared to my Glock 27,the 365 has better ergonomics smaller package, better trigger, I shoot it better, easier to carry,(for me). With the 12 round mag it truly is an amazing little pistol, it totally blows my mind :-) nothing negative about the 10 round mag and ergonomics. I even like it better than my Glock 43, and I love my 43. Would I bet my life on it, I need to put more rounds through it And see if anyone else has any major issues with it. I don’t carry a spare mag so the issues I had do not concern me, But they need to be rectified.
