A couple years ago I grabbed a box of .45GAP ammo off a shelf and didn't realize what I had until I got it home. What I intended was standard .45ACP for my Glock 21. By then it was too late as the store had a no-return policy on ammo. I've tried putting it up at a couple shows with no luck. I know it's a real odd bird but someone out there must have a Glock model that uses it. I'll take any reasonable offer.
