I carried either a Browning 9mm or a Colt Trooper MK 3 in the .357 variety.
When I was running on the Fire/Rescue I always had the Browning in a pancake holster in the small of my back. Since I always wore a fire dept. jacket, it was easy to conceal, slim, lightweight as well as easy to pull out if needed.....
nothing like going to a backwoods bar fight and being 10 minutes ahead of the nearest deputy.
The .357 was a bit of overkill and I always felt like it I had a 5lb. weight hanging from my left arm pit but it sure did stop the guy that pistol whipped and robbed me at gunpoint. He will never rob anybody else.
