.357SIG is not a good subcompact round. It's not even a good compact round. 40K PSI pressure, bottleneck cartridge...it's just not that efficient. No one wonders why there aren't any subcompacts in 7.62x25 or 5.7x28, right?

It really comes alive at about 5", a full-sized duty gun. Most factory ammo in the 125gr range clocks at about 1300fps from a 3" and 1500+ from the 5". That's a velocity jump you usually see out of, oh, I don't know, the .357 Magnum (funny how that works!). 9mm+P 124gr gains about 125fps in the same scenario. Plus, flash and blast are that much less. A Glock 24 or 35 with a .357SIG barrel would make a great home defense gun platform. Not that you see many 24s in the wild.

Conclusion: most of the handgun action is in compacts and subcompacts and the .357SIG is only slightly better than a 9mm+P from those guns, with lots more flash, blast, and recoil.
