Retired LEO here. The revolver is still a fighting handgun. 2 revolvers are a fighting pair of handguns. Add a Modern 9mm, 40cal, or 45Acp, you are very well armed!
I prefer a G19, or a G21 with hi cap mags. BUG is a 442. Pocket, weak side, crossdraw, IWB, or OWB, not a problem.
Retired to me means carry both. Cell phone to "call it in" if you cant get around it.
If you are grey haired, wear cargo shorts all the time, Hawaiian Shirts, and ball caps with Baseball or other logos,(not police or gun logos), you can be a retired Police Officer with firepower concealed. Yes you can Open Carry, I don't. If hunting or Disaster declared, new game on. May dust off my Moss 500- 18.5 in , 12ga, with accessories for home
protection. It plays well with J Frames, K frames and all Glocks. we are prepped for all here. Good luck. Keep your Js, Ks, Ls, and others. They work.
