.45 GAP vs .45 ACP

[BluesBear]

Double stack 1911 45 GAP might be a real nice grip.

Why am I reminded of the Browning BDA double stack .380?

Oh yeah that was a huge success wasn't it?

Perhaps not the model with the browning emblem, but the Beretta 84's have done pretty well. I bought an Inox 84 FS for the wife and she adores it. IMO, it is an excellent purse gun for a woman. Small and light with 13+1 capacity. Of course, she now prefers the S&W 4506.

Ha, I was thinking more of a Hi-Power grip dimension with a 1911 SA trigger.

Could be "sweet" if it worked!

Just going out on a limb to see if the GAP has any use in a 1911...it may not!

I wonder if the .45 GAP can load a 260gr LSWC and shoot it at 860 FPS as the .45 ACP can?

According to one "expert" the GAP doesn't drop out to 380 yards, so I guess it wins the long range contest.

Is it possible that .45 GAP can achieve higher velocities from a 3" barrel, using lower pressures?
For one thing, in an auto, it will already have a 0.1" advantage in actual barrel length.
Second, with the modern powders, there's less empty space left over in the cartridge, right?

When the GAP was released, it was explicitly stated that the cartridge wouldn't function well with heavy bullet loadings. In fact, at the time of the release that limitation was intended to apply even to 230gr bullets. However the ammo manufacturers found a way to get the 230grainers to work well. I suspect that going heavier than that would be a problem.
