So I have a P365 that has been flawless until now with everything I've fed it. I had this 50 round box of Tula ammo (steel cases) that I thought I would burn first and... Pistol failed to return to battery and was stuck. I had to forcefully hit the slide and it finally went to battery and fired the rest of the rounds with no problem. So far, that has been my only issue with this gun after 750 rounds. I'm thinking that it's no big deal since it seems ammo related. However, this is a gun I carry often and it's in the back of my head... My other carry is a G36 with over 3,500 flawless rounds through it but I have never used steel cased ammo on that one. Any other experiences out there with Tula steel?
