Ok, so I just read up a little more on the P345 and discovered the magazine disconnect problem. I read that If you "clean" the rear sight and just so happen to forget 2 pieces its good to go. Just want to clarify that if you do this, will you be able to dry-fire without a magazine and everything will be good to go? I dont intend on dry firing without one anyways but I dont want to take any chances. Also how easy is it to disassemble an reassemble the rear sight? Im new to guns and dont want to mess anything up. Will I need and special tools, or can I just sit in my living room and do it.
