What if you could take the .45 acp make it more compact allowing for it to fit into a smaller handgun, but still somehow retain the same relative power? That was the idea behind the .45 GAP pistol cartridge designed in 2002 by Ernest Durham. The acronym G.A.P. stands for Glock Auto Pistol and the first gun chambered for this round was of course a glock. By "relative power" we mean power relative to the size of the cartridge and bullet.

The 45 G.A.P. a relatively new cartridge so we'll see where it goes from here, but for now a just few law enforcement organizations have picked up the round and we'll just have to wait and see how things pan out. Very few public ballistic tests have been published as well, this makes it hard to make a informed decision.

The cut an dry is that the gap performs very similar to the lower grain 45 ACPs. However people are saying that because of its size it has less powder and so is going to have more of a drop at a distance. The test we've ran using just the numbers show that this is not the case. Please see the ballistic chart below, or better yet create your own comparing the 2 rounds. Just make sure to choose the same manufacturer, same bullet tip, same grain. We compared the .45 GAP Winchester Silvertip HP, 185gr and the .45 Auto Winchester Silvertip Hollow Point, 185gr and there is just a 3" drop difference at 500 yards. This result is not really what we expected to see, but seeing as the ballistic coefficients are nearly identical it's not that surprising.

In summary the 45 G.A.P. is a good round trying to replace a great round with lot's of history. If someone comes out with a great .45 G.A.P. pistol that can justify the need for the round and that pistol were to get lots of publicity then the .45 G.A.P. might become a more popular round.
