Is the .45 GAP (.45 Glock Automatic Pistol) a dieing or NEAR DEATH caliber?

[Gryffydd]

I'd be interested in grip size numbers between a .45ACP XD and a .45GAP Glock. The .45ACP XD is perfectly comfortable in my relatively small hands. The Glock 20/21s are no were even close. I haven't had the chance to personally check out a GAP Glock.

Try out the Glock 21 slim frame and let us know what you think.
