I found a Glock 21 (.45acp) for sale. The guy wants $700 for it. It comes with a black Safariland holster, 6 mags and a 4 mag belt pouch. Is this a fair price,or is he a little on the high side? I've only shot one Glock, and that was years ago. I am wondering if it would be a better "house" gun than my 1911A1.
