The 45 GAP is a specific caliber for Glocks only. It was the biggest mistake they ever made.
It is a higher pressure round, that can be accidentally loaded and fired in a 45acp .
They run higher pressures and can hurt the gun and shooter if fired in a 45acp.
Normally higher pressure rounds are loaded in longer cases that won't fit in other lower pressure guns

I have never seen either one. What the hell are these lol. That 45 gap would have the same gn bullets as any other 45 just a different charge?
