I carry a S&W model 411 in .40S&W that I bought several years ago. It's an old Police trade-in, and I was able to buy several extra magazines from CDNN. I like the .40S&W round and prefer it over a 9 mm for power. I have mostly Hornady Critical Duty and Critical Defense ammo in the mags I also have a Glock model 22 in .40S&W with several extra mags.
