Thanks guys, I get the whole mag size thing now. This really opens up a bunch of possiblilites for pistols, I appreciate the info.
Sunray, my question is based on a list of pistols permitted for use on the ISPC site. It simply states there that the Browning Hi-Power is not usable in competition. The "mag safety" would be intact on a new pistol I assume, but I'll check when I'm on the website or at the gun shop. Again, I appreciate the info guys, thanks. -Ric
