I have had my CHP for 25 years and at various times carried a 38 snubbie hammerless iwb, Colt Commander 1911 horiz shoulder, and 6" 357 revolver vert shoulder. Now a days it is usually a full size auto vert shoulder, or slim 9mm horiz shoulder or appendix carry. I have been toying with the idea of buying a Bond Arms Derringer, specifically the 4.25" barreled Ranger in 38/357 with matching cross-draw belt holster. This two shot gun is more popular in 410/45LC, but I have a sh!t load of 38+P/357 and zero 410/45LC. This would mainly be a kit/range gun as I could order any of 16 available barrels for it from 22lr to 45acp. I like to shoot 1" target dots, so this gun would be a real challenge and might be frustrating. This gun has some potential as a self defense weapon too. Considering the SD limitations of the Bond Arms Derringer: i.e. two round capacity, slow single action presentation, limited accuracy, and slow reloading, I decided to reconsider carrying a 357 revolver, something I have not done for a long time. Recently I have been toting my S&W 686-6 4" barrel 357 mag in an Uncle Mike's Vert Side-Kick shoulder holster (size 2) with two speed loaders. I shoot this gun very well in both fast double action and slow-aimed single action modes. That is 18rds of 357 mag on tap. The man-stopping power of the 357 mag with police is legendary. Much better than the 9mm I often carry. This shoulder rig is very comfortable for all day carry, working, driving, sitting, laying on the couch, using the bathroom, etc. The draw is fast and the reliability is excellent. Retention is very good and instinctive. It is surprisingly discreet with a jacket and prints much less than an iwb small of the back medium size auto. I guess I could use the Derringer as a backup gun (for those rare shtf situations) or deep concealment pocket primary when I can't wear a jacket. It is a good idea to have the primary and backup share the same caliber.
