I own a full size .40 USP (which I love). Thinking about getting the full size .45 acp. I know that the full size 9mm and .40 have polymer magazines whereas the compacts all have metal magazines. Are the full size .45 mags metal or polymer? Also, it is my understanding that the .45 was introduced in 1995. Is it true that HK produced a limited number of 12 round magazines prior to the ban in 94? Thanks for the help.
