Greg, think of the GAP round as being a short 45acp. It has the basically the same ballistics as a 45acp.
Just took delivery of a new XD-45 LE yesterday in OD Green. It cost $429.00 and was ordered thru Richland Shooter's Supply.
This pistol looks and handles great. The photo posted up above doesn't do it justice. I've got ammo and targets for a trip to the range this weekend. Unless I get there sooner.
The anticipation...
Btw, this is the 1911 that's next on the list:

I'd probably swap out those stock grips for Gunner grips in a different color.
