You mean those Xtreme Defenders? Yeah, the heaviest are 115s. I'd just use hollow points.
My brother came over and we went out for a burger. I told him about the Underwood ammo and I wanted to try 'em out so we went to the range today. I grabbed 25 rounds of 9mm 124 NATOs to take along with the Underwood, one box of 9mm 124+P and one box of 40sw 155.
I have an HK USP V1 9mm and a Sig P250c 40sw for the tryout. I let my brother shoot the 9mm NATOs while I shot the Underwood 40sw 155s. I left 5 rounds for him to shoot the 40.
After that we each shot ten rounds of the Underwood 9mm 124+P then we went home.
On the way home my bro said, "Hey, that 40? That'll put 'em down won't it?" and I said yeah, it's my new carry ammo bro.
