The Sig round really doesn't have a real world advantage over the 9mm UNLESS you're talking about vehicle penetration (glass/sheet metal). Gotta agree with Dr. Roberts there.

Also real world, back before retirement, we'd invite the local VA State Police in for our night shooting work. Give them a chance to do things in dim light. After we got over the muzzle blast thing, we realized that the muzzle flash lit up our targets. We'd wait for one of them to fire and then shoot at the illuminated targets. Did wonders for our scores, the staties weren't shooting for record.

Hopefully some of you enthusiasts will realize it also locates the user for anyone with whoever you may have shot at.

I do grant that you do get the mixed blessings of a flash bang without all the restrictions of the real thing.

BTW, something to consider, I have a "moderate" hearing loss due to limited unprotected use of firearms. Along with a 24/7/365 concert from tinitus [screwed up the OSHA reports on retirement ].
