I think a snubnose for the .40 S&W would be a good concealment gun. Light, easy to conceal, a little more power than the .38 Special and (from what .40 S&W owners tell me) accurate.
Want to see Colt produce the SAA full-time so it could be offered at a reasonable suggested retail price ($600 or so). I haven't seen the Colt Cowboy but I don't hear much good about it. I guess quality is a huge problem. Love to have one in .44-40 to complement my repro 1873 Winchester rifle of that same caliber.
Love to see Smith & Wesson reintroduce the Model 15 Combat Masterpiece, in blue. This .38 Special revolver is a joy to carry and shoot. Also love to see the same model offered in .32-20 or .32 H&R Magnum. Be nice to have a .32-caliber, high-grade revolver with adjustable sights, in both 4" and 6" barrels.
Remington should reintroduce its cap and ball revolvers in .36 and .44 caliber and its Model 1890 cartridge revolver in .45 Colt, .44-40 and .44 Special. I'd buy one like THAT if it were in .44-40. Why Remington hasn't reintroduced its old-timey revolvers is beyond me, considering that Colt and Smith & Wesson have.
Come to think of it, why haven't Colt, Winchester, Ruger or Remington reintroduced a hammered shotgun for the Cowboy Action Shooting crowd?
Seems like a side-by-side shotgun in 12 and 20 gauge, with 22" barrels, straight stock (no pistol grip), hammers and case hardening on the receiver and steel buttplate would be good for CAS, hunting game in thick cover (grouse and rabbit comes to mind) and for home defense.
Ahhhhhh ... what am I saying? They'd just muck it up with 28" barrels, a fluorescent bead, stamped checkering, a safety that required the entry of a three-digit number before disengaging each time and a stock made from Chinese ammo crates.
We all know what is needed. Trouble is, the factories don't give us what's needed, they give us what they can hype (witness the Remington Etronix rifle with electric ignition, the .17 Rimfire and the S&W .500 revolver).
