This may be totally a noob question so bare with me here. I know some types of handguns have various types of mags that they would except. Like my M9 uses the new "sand resistant" mags but I could easily use another 92 mag or something along those lines. I just bought one of my pop's 1911s and he only had one functioning mag with it. I could just get a few more mags of the companies more familiar to me but after doing some curiosity research I started to get overwhelmed. I know enough to decipher between good and bad manufacturing but with all these companies nowadays making 1911 mags, or rather any mags for the common handguns in general, how the hell am I supposed to pick and choose which ones to purchase? Does it just become personal preference at this point, to some extent?
