I want to buy a m&p 9, and it will be my home defense gun. I'm just a little scared about the mag catch prob. is this with the fullsize guns or just the compacts? I can't seem to get it out of my head, needing the gun someday and not fully trusting the mag catch. I'm sure it's not that big a deal, but there are just so many people gripping about it. What do I do?
