    .45acp, .45 auto rim, and .45 gap all use the same diameter bullet, but are dimensionally different. The .45 GAP came almost 100 years after the acp, and is shorter. You have to create new loads every so often to sell more guns....

    The case is shorter and stronger in the GAP. Basically you end up with identical performance in a smaller framed gun.

    So basicly it was done this way like someone said, to sell more guns? Is one of them more used then the other or maybe easier to find ammo for?

    ACP is infinitely more popular than the GAP. For the most part ammo is the same price, and in a lot of places equally available. If you're smart and get ammo online anyway, then there's no difference. Plus the GAP Glocks are usually available at a steep discount.

    That's not the reason. The .45GAP (Glock Auto Pistol) was developed in response to demand for a .45 caliber hand gun in a smaller sized frame. The GAP framed pistols are dimensionally similar to pistols chambered in 9mm. &.40 S&W. .45ACP requires a larger platform. For many people with smallish hands that platform was uncomfortably large.
    Do not assume that because the GAP has a shorter case that it is less powerful. Not so. The two are ballistic twins.

    Good post!

    One is no better than the other, they each have their own place in the world of calibers.

    You know I see this alot on here, If you really think about it cant any question you want to know the answer to be googled, if so then why even have a forum?

    The GAP models seem to be easier to find than the ammo around here. I wouldnt give up my G38 but when the Gen4 G38 I may have to consider a switch

    This. The GAP is an improved .45acp relying on higher pressure (using faster/newer powder) get equal velocity. The smaller load fits in smaller guns of the 9mm/.40 platform. It's a great concept that's struggling (IMO) to really catch on despite Glock best efforts to market it. Thus, IMO, it remains a novelty semi-auto load like .357sig and 10mm. Like anything novel, it has a small, loyal, vocal following. However, until it's mainstream most pass on it, including myself.

    Generally, I use Google to find out facts, like the dimensional and ballistic differences of those two cartridges and the forum to get folks' opinions and the benefit of their experience. Not a big deal.

    I not a fan of the GAP, but I guess it serves a purpose for those who feel they benefit from a slightly smaller grip.

    .45 GAP is meaner than .45 ACP.....

    [​IMG]


    And shorter.....

    But they are not interchangeable!

    Other than that, they are pretty similar. :)

    The main difference is that the 45ACP is a man stopper and the 45GAP is only a practice round, that's designed to punch innaccurate holes in paper.














































    :tongueout: That ought to get the Gappers fired up...:rofl:

    In reality, they are both just as good as each other for SD use. In a Glock, by using the 45GAP load, it will let you use a gun that is the same size as the G26/27, G19/23 and G17/22. Calm down Gappers and.............:panties:

    Yeah, you know, it's basically the same round, except for the GAP round suffers from "little man syndrom". :rofl:
