I can’t think of any agencies in SE PA that issue revolvers. I believe Philly PD still allow officers hired before a date in the 1990’s to carry them. There are a few PA State Constables who carry a revolver. Ocean City Maryland issues revolvers, maybe Model 64’s, to the officers who work the summer season only.
Oh, and I still carry a revolver. My small county agency requires us to provide our own firearms. Our current firearms policy authorizes double action revolvers, and all semi auto pistols. This year I qualified with the SP-101, 340, 12-2, 64-2, 65-3 and Colt auto’s in .38 Super and .45ACP. I also qualified with a Glock 32. The other investigators in my unit carry striker fired pistols, either Glocks or M&P’s.
I feel well armed carrying a revolver, and have never felt ill equipped in almost 28 years. I can shoot a revolver really well, and I’ve been shooting them a long time. My job primarily involves knocking on doors and talking to people. If I need a gun it will probably be at point blank contact range, where a revolver has the benefit of not being pushed out of battery. If I need more than five or six shots I’ll use my back up gun. I realize I’m viewed as a dinosaur by most people, but it works for me.
