I used to be one. Fine job if you like shift work, midnights, low pay, office politics, associating with the local scum, opportunities to get hurt, missing out on family time and holidays, and going to traffic court after working all night.
Anyone who says they have no experience with handguns should not opt for a semi auto. Your handgun is a revolver until you train up. I would suggest a Ruger SP-101. My carry is a Glock 26. I am a Law Enforcement Firearms Instructor.
