Hello could someone tell me who are the better names for aftermarket magazines for ruger mini 30, fn five seven, para ordnance p12, and what are the better names in general. Now someone said pro mag is not good others say they are. What is the truth? I'm basically new to the whole world of aftermarket accessories and ammunition since I always shot other peoples guns. I have recently come into a nice collection and would like to get all the information I can. Any input would be appreciated. Thanks.
