Yes, my better half uses these.
1650 FPS, 242 FT LBS OF ENERGY IN RUGER LCP
I know the local armorer for the Vegas Swat. His opinion is that modern JHP defensive rounds in 9mm are as good as 45acp in putting down a perp.
I prefer 40s&w JHP defensive rounds, they have just as good penetration, FtLBS of force, and a ccw pistol can carry 12-14 rounds instead of 7-10 of 45acp.
Guns I like
H&K P30 lem
Walther PPQ
Sig P320
Beretta PX4 Carry
40s&w is insurance, but really if 9mm wasn’t sufficient then why NATO, most police and the US Army using it.
Modern Talon type bullets are fearsome.
