I’ve owned a couple of Sigs in my time, but there’s something about a .45 with a 13+1 capacity that just warms the cockles of my evil little heart. Especially when those 14 rounds are 230gr Hydra-Shoks.
What about a .357 SIG for a concealable. The goal on this design was to equal the performace of a 125gr .357 Magnum load. Muzzle vel of the SIG is about 1450fps on a 4 inch barrel, 792Joules energy (highest I have seen for a .45ACP is about 700Joules).
Only problem with the 357SIG is the muzzle flash and noise. The 45 ACP makes a good ‘silenced’ device, hard to do that with the 357SIG
PS: The .357SIG is supposedly standard issue for special agents of the Secret Service. Scary part is that is it also standard issue for the Treasury Inspector General for Tax Administration (I guess they really want the money!)
For a .45 ACP, look at CorBon JHP. Lighter bullet, higher velocity. Penetration is less within human target while delivering almost 50% more shock energy than a HydraShok.
