Switching from 40SW to 45 GAP

[PhysicsGuy]

Don't the .40 SW and 9mm both develop about 35,000, not counting the +P in 9mm?

I believe, maybe mistakenly, that the 357 Sig was developed to operate like the 357 mag only in an auto. I "think" the ballistics and caliber are very similar.

I "think" the sig is almost a necked down .40 with a .357 bullet in it. I "think" the sig case is a touch longer than a .40, but not much.

I'm not in the mood to check my facts much, am I?

The .357 sig is "supposed" to develop .357 mag power, but only matches light magnum loads.

Also the .357 sig is a necked down .40 S&W, which itself is a shortened 10mm. But IMO if I wanted a necked down handgun cartridge, I would go with the 9x25 Dillon (10mm auto necked down to 9mm), which is basically what the .357 sig was trying to copy.

I just never saw the need for another caliber. I already have too many - 22lr, 9mm, 40 SW and 45 ACP and that's just hand gun autos for pete's sake!!!!

.45GAP is a solution looking for a problem.

Kinda' what I think. No, that IS what I think.

If you want a new caliber, just go buy it. But in this instance, don't be surprised if it's a hard one to find in a few years.
