I picked these beauties up just in case they ban high-capacity magazines. The background check just came back today, in which it took 10 days. Usually it takes about 15 minutes. The H&K P2000 is 9mm and the Glock is model 22 (full-sized .40 S&W). I had a Glock 19, but getting the P2000 made it kinda redundant, but I still wanted at least one Glock.
