[edit] Versatility vs. ACP?

Can someone provide a sourced explanation as to why the .45 GAP is 'less versatile' than then .45 ACP? 24.3.142.198 13:25, 8 April 2007 (UTC)

[edit] Conversion Kits

Just wondering if all the gun makers will be making .45 G.A.P kits,..or will they just make a new model line for that cartrige ?

    I have a Springfield armory XD-40 and I'm ready for a big .45-Cal.

[edit] Legality & Mexico

I am not 100% clear on this but the article lists Mexico as a place the round could be useful for civilian use. However according to this article (which is somewhat confusing in itself): http://en.wikipedia.org/wiki/Gun_politics_in_Mexico A civilian cannot own a handgun round larger then a .380. Can someone clarify? --Nicklinn 15:08, 28 February 2007 (UTC)

The idea is that, in Mexico, as per Article 10 of the Constitution, "military" calibers aren't allowed for civilian use. The .45 GAP is new and has not yet been formally named a "military" caliber by the mexican government. As such, in theory, the .45 GAP may be ok. But don't count on that. Besides, it's all moot I think. Regardless of what the "letter of the law" is in Mexico, in practice you've probably got a 99% chance of going to prison for even being in the same room with a firearm. —Thernlund ^{(Talk | Contribs)} 21:14, 28 February 2007 (UTC)

That's as maybe, but this is all unsourced speculation/original research about the state of Mexican laws vis-a-vis handguns. Provide a source on this, otherwise leave it out. 24.3.142.198 13:26, 8 April 2007 (UTC)

[edit] 230 grain bullets

I took the 230 grain bullet velocity out and put in 185 and 200 grains. I was wrong when I commented that no one loads the 230; Winchester does, but at a lower velocity than their .45 ACP 230 grain loadings, where the 185 grain loads are about the same for .45 ACP and .45 GAP. I think that Winchester offers the 230 grain bullet because they don't have a 200 grain bullet, and they want to offer more than one weight. The 230 grain GAP loading from Winchester generates 355 ft-lbs at the muzzle, a good 60 ft-lbs lower in muzzle energy than the 185 grain loading, while most .45 ACP 230 grain loadings generate over 400 ft. lbs. and .45 ACP +P 230 grain loads can break 500 ft. lbs. While the Winchester 230 grain loading is actually slightly higher in velocity in the GAP compared to the ACP load, this is also comparing a 23kpsi load to a 21kpsi limit on the .45 ACP, and the .45 ACP is probalby nowhere near the limit. A +P load in .45 ACP will almost always beat out the GAP loading because with the fast powders used in pistols, a larger chamber lets you flatten the pressure curve and get more area under the curve with the same peak.

[edit] .45 GAP Accuracy

I fired a Glock 37 in .45 GAP immediately after firing a Glock 31 (357 SIG). I fired as well with the .45 GAP as I did with the 357 SIG--very tight groups. In fact, just by feel, I couldn't tell the loads apart. If a .45 ACP pistol grip is too large for your hand, then .45 GAP is worth a try.
