    The .45 GAP is shorter than the .45 ACP.

    The 45 acp is for men and the 45 GAP is for women.

    there is a law in some euro-peon countries that you can not own millitary calibers the gap fills this roll.

    Kind of like the .222 caliber rifles. I see, thanks Oren. I was looking at some glocks and saw a few chambered in .45 GAP.

    Here is a quote out of "The Gun Zone" on that....
    Can the .45 GAP be fired in a .45 ACP semi auto? Under certain situations it might work but is not recommended. Both calibers headspace on the case mouth, but the short GAP cartridge cannot reach the chamber headspace index in an ACP barrel, although it might headspace off of the extractor sufficiently. Since both calibers have a similar external taper, the GAP might seat in the chamber correctly for the firing pin to ignite the primer as expected. If not, the primer could be pierced by the firing pin, or the firing pin may not have sufficient force to ignite the primer. Instead, either buy a specific .45GAP pistol brand, or buy an aftermarket .45GAP barrel as long as it functions reliably with your .45ACP pistol brand. Bar-Sto has announced that they will produce .45 GAP barrels.

    Can the .45 GAP be fired in a .45 ACP revolver? Yes. While it is not officially approved by S&W, a number of revolver owners have reported very good success using moon clips (more detail later in this article).

    Glock designed the GAP round for people with small hands because the shorter cartridge means a smaller grip area.
    People with smaller hands couldn't use the Glocks chambered for the 45 acp very well so the GAP was Glocks answer to this small problem.
