Don’t know what the feds are carrying. My older brother carried 5 days a week for LAPD for 17 years and never put a hole where he didn’t want it to go. Of course that bad guys put 2 into him, but he managed to go home alive at the end of his shift, so that counts as a win. I don’t own glocks, but have plenty of others, and never manage to shoot myself.
SS tends to carry Sig 229 pistols in 357 Sig caliber.
