Why bother? Because you can get better combination of energy and expansion from a 185gr .45 ACP +P defensive round than you can in:
9mm
.357 Sig
.357 Mag
10mm
.40 S&W
Show me a round that has better numbers than this:
500 ft-lb of energy
.75" diameter after expansion
100% weight retention (in a published test)
... that I can shoot in a compact auto. And I'll be heading to the store to get it....
The only reason I would choose something over the .45 ACP +P for a manstopper would be if you need to shoot through heavy clothing, windshields, light cover, etc. In that case I would choose the 10mm.
357 SIG 125 gr. Ranger 500ft lbs .75 expansion havent found a published weight retion yet but ill keep looking
