One more point- SIGs are right handed guns. Decocker sucks.
While one can operate ( shoot) one left handed, making one safe is a fumble prone operation require digital gymnastics or two hands...
The CENTCOM Forward armorer tried to issue me an M11, (P226) a long time ago. Had to take an (sorry excuse for a handgun) M9 instead.
Hadn’t considered that... must be my “right supremacy” ;)
