Misc. Friday Ramblings

It's alive, alive, weird Friday...

Obligatory Friday gun stuff!

The Springfield XD in .45 GAP.



From a THR thread:
The .45 GAP operates at a higher chamber pressure than the standard pressure .45 ACP. At those higher chamber pressures, the .45 GAP has roughly the same ballistics as the .45 ACP does at standard chamber pressures.

When you increase the .45 ACP to the higher +P chamber pressures, it has a slight ballistic and effectiveness advantage over the .45 GAP. For example, the .45 GAP and standard pressure .45 ACP Ranger T both have a MV of 885 fps (and have identical penetration, expansion and intermediate barrier performance figures). When you up the Ranger to +P, the MV jumps slight over 100 fps to 990 fps, and the penetration, expansion and intermediate barrier figures improve (e.g., 2.5" more penetration against heavy cloth and 1.6" more penetration after auto glass).
