    .45 ACP vs. .45 G.A.P.

    I know it is hard to take on the established brand, but could someone tell me what the real difference is between a .45 ACP and .45 G.A.P.? Why did it not catch on?

    The GAP was created so that you could have .45 ACP ballistics from smaller framed guns,9 mm mostly.

    Its a bit shorter so that they could cycle through 9mm sized actions.

    Although its a cool concept, it was an answer to a question that no body asked. I think the fact that the ammo availabilty is somewhat questionable has as much to do with its lack of popularity as much as anything.

    The .40 and the .357 Sig blew them out of the water. The GAP never could reach .45acp ballistics, and the others put them out of business.

    See what I mean about the .357 Sig? With the new Double Tap 147gr rounds, it's even more impressive! Pushing over 1500fps, 650 ft-lbs, 14" penetration with 100% bullet retention. Why would you carry a .40?

    And the cost of the .45GAP made them obsolete also.

    The REAL difference? About $5 per box of practice ammo and about .01 of the stores that carry ammo carry it.

    Why would anyone want to buy some weird round that's hard to find ,costs a bundle ? I'll keep my dependable 45acp that been around for 100 years and proven in two world wars and a couple other wars.

    Back in the days when the only way to really increase the effect of a gunshot wound was to go to a bigger bore, the GAP would have had a reason to exist. Today, it fills a very small niche, and apparently not a commercially viable niche.

    The .40 S&W, arriving first, stole much of the GAP's potential thunder. (The same can be said of the .357 SIG, even though, of course, big-bore devotees may not like the .357 SIG.) Had the .45 GAP arrived first on the market, it is certainly possible that it would have become a widespread choice among U.S. law enforcement.

    I have a deep sentimental attachment to the .45 bore size, but see little reason for the GAP to exist, and certainly no reason for me to buy a weapon so chambered.
