Hold on.... Maybe I misunderstood what you said ..'I’ve even watched videos and am doing it all right...can’t figure it out.
Yes, the baseplate! I’ll give this a try, thank you!Wait...are you talking about installing the baseplate on the mag...or the magazine in the gun? 🤔
If the former, then it’s not installed fully until the round tab is flush with the bottom of the baseplate (regardless of what you hear). It sounds like it’s not all the way in. Try taking a small punch and pushing on the tab while you wiggle the baseplate a bit. It should seat at the way and not come off.
That is one of the many reasons that I converted to the XL grip module for my P365.only problem with my 12 round is when slam it in the grip module and catching my pinky in it at the range.......ouhhhhhhhhhhhhhhh...hurts like hell...damn that short stubby grip...lol....but love my p365...love hurts
