i have an uncle mikes shoulder holster meant for a sig or p99 sized pistol, (i bought it for a p99 air pistol) i think it's size 15. the reason i really want a pistol, is my tac vest has a cross draw holster on it, so it might look dumb empty. personally i'm not a 1911 fan, as every time i pick up a gun mag, it has half of it's articles dedicated to the latest clones of the 1911. 1911s feel the the ak47 of pistols. i much prefer newer styles of pistols.
i also love pistol shooting, so a sidearm would be fun.
