I used to open carry when I lived in Yuma, Az. I carried a Ruger 9mm revolver. Although I much pefer a .45 long colt, but could not afford such a beautiful sidearm..
The reason for that is that there was NO gussing that I had a sidearm, and would use it if I had to! I had several years worth of classes on the use of lethal force, while in the MARINE CORPS [10 years,7 months,4 days] & working as armed security officer in St. Louis Mo. [over 12 years] then I carried a Tarus .38 [modeled after the Smith model 10] and all of that time, I had to pull out my sidearm only 3 times & NEVER had to pull the trigger, except on the range 3-4 times a month......
A 9mm *REVOLVER*????
Yep, I’ve got a 3-inch 9mm Ruger SP101 (rare as hen’s teeth), and a Ruger Blackhawk Single Action convertible that is a .38/.357 with a matched 9mm cylinder. Doesn’t need moon clips.
