I have often on this site argued that the 45GAP was an interesting concept that had very little practical application. Increased awareness and study recently caused me to pick up a used G37 (w/ 3 mags) at a gunshow yesterday. I paid $400 for a model so unused that another vendor - who repairs/makes alterations on Glocks - exclaimed on his examination that "this gun has never been fired." So, here I begin a journey into the world of a new caliber. Like Sweeney said in his book: if this cartridge would have come out in the late 1980's - the (handgun) world would be quite different." Question. Have some access to ammo locally, but who does the best mail order/prices for the GAP? Able, Midway, Cabella's, CT Dirt, Georgia A...others? Thanks in advance for your replies.
