10mm vs 40S&W

I may be wrong because I've never owned or fired either but my perception is that of comparing the 38Spl and the 357 Mag.

Now I have been contemplating a larger bore pistol then the 9mm's I own just to have something larger. Though my thinking has been more along the lines of either the 40 S&W or the 45acp. as I don't believe I'd need a 10mm version.

Those that want to argue the energy and velocity side of things should indeed watch the Harrel video as mentioned earlier. There is a wide range of differences depending on what maker of ammo you choose in the debate. Loaded up to its potential, (by the factory ) the 10mm is serious medicine. As loaded by some mfg's, it is a weak sister an no more gun than a .40. To boot, some .40 doesn't really make grade either.

Another aspect are the 10mm guns themselves. As a rule, the large frame Glock's are a handful, as in big grips and trigger span. That leaves the 1911 varieties, which are SA guns with manual safeties,not everybody's cup of tea. There are the SIG "P "family, but I've not handled a SIG 10mm, but the big SIGs (P220-226) don't fit everyone either.

I'm inclined to suggest the .40, even though I'm not a real fan of the caliber. The guns will fit most anybody that can handle a double stack 9mm, the guns are available in simple to run striker or DAO (as opposed to SA safety) mode, and one has more gun, theoretically, than a 9mm.

Not really the 40 and 10mm are much closer in terms of pressure 35K psi for 40 and 37.5K psi for the 10mm, where as even in +p garb the 38 special is only 20K psi vs 35K for the 357.
Much wider gap in performance.

Nice thing is, wither 1250 or 1198 fps, a 180 defiantly puts the .40 into the league of a hot loaded .357 magnum.

No autoloading pistol round will ever equal the .357 Magnum 125gr SJHP, for the .357 round has soft lead in the front of the bullet. The pistol bullets do not, for feeding purposes. The .357 125gr SJHP will always expand well, as we have seen historically.

There are many bullets that expand every bit as reliably as the 357, some even better.
 
All of the "one shot stop" stuff, if you believe it, had ratings that divided the best performers by tenths of a percent.

It's not like 125gr .357 was 99% and 10mm or .40 JHPs were 50%, there were a dozen or more rounds that were in the high 90s.

I distinctly remember one guy saying that his research showed .45 ACP/230gr Federal Hydra-Shok, when fired from a 5" barrel, had 100% one-shot stops.
I don't know how that could possibly be true, unless that sample size was extremely small, but if there's any truth in one-shot stop "ratings", 95%-99% are essentially the same.
