I will be purchasing a new weapon here in the coming months. I was considering the Glock, for a few reasons. First, their reliability. But the second reason, and the bigger reason, is I will also be purchasing and carrying a smaller backup, that will also be used as a concealed weapon. A friend brought it up that it'd be optimal if the primary and backup gun could use the same magazines, if sh!t really hit the fan and I not only needed my backup, but needed more rounds.
I want a 45 caliber, for the slower velocity and higher damage infliction. The recoil isn't an issue (I honestly can't tell a difference).
So I was looking at the G21 and G30 as a backup.
However, a friend today said that while the magazines do interchange, the large capacity mag will not lock into the compact G36. So I'm looking for opinions regarding this, and the weapon choice in general. Thanks!
