The .22 magnum has been a longtime favorite of mine; low recoil, out penetrate a .357, carry a lot of ammo easily, etc.. I had a S&W 351 PD (1 7/8" bbl.) but learned the .22 magnum in short barrels is all flash & no performance, there just isn't enough barrel to burn up the powder in that longer cartridge. The muzzle blast in low light was just short of Hiroshima in 1945 but offered no more velocity than a .22lr.. A 3" model 650 is the shortest I've had any performance with. Not much available in .22M snubbies @ any price, most folks discover they really don't work out & replace them w/ .38's of .357's..
