Hello to everyone as I'm new here! I just recently bought a PT-140 and love it. I took it to the range last night and had the magazine pop out 3 different times after firing. The magazine was not repeatedly falling out, however. Thinking that I maybe was hitting the mag release button, I changed my hold and it didn't come out again. Just to make certain that the mag release is not broken or chipped on my gun, is the magazine release supposed to have a 45 degree angle at the corner of it (looking up through the magazine well or down through it when the slide is open) or is it supposed to look square at the corner? I don't think mine is broken, but I thought I would check with someone more knowledgeable. Thanks again for everyone's input here at the forum--I've learned a ton so far reading past posts.
