The venerable .22LR & .22MAG have been around for a while. I suspect I'd naturally obtain the best performance for .22LR from my 6" & 4" Ruger pistols.
When I decide to slip a NAA 1 1/8" .22LR or .22MAG in my pocket, the LR is loaded with either Mini-Mag's or Stingers, and the MAG is loaded with Hornady CD (because I can't find any of the Speer GDHP locally, yet).
I don't look for either diminutive .22 to meet the oft-mentioned FBI guidelines for duty ammunition, but then they aren't duty weapons, just emergency "Onion Field" type guns.
I have a 2" Black Widow (LR/MAG conversion w/low fixed sights) on back-order, and once I replace those huge, gaudy BW grip stocks with one of the standard rubber sets (either the 1-piece slip-on or the stocks which are secured with a screw), I'd like to find some of the GDHP .22MAG, if only because it's been optimized for the 1.9"/2" barrel of the common .22MAG snub revolvers.
Having the conversion cylinder might make it handier for being able to take the LR cylinder along for some (lawful) plinking, but to carry it with the MAG cylinder. Beats taking both 1 1/8" NAA revolvers along on a trip. I also like the BW model for the way the cylinder pin is retained, and the slightly beefier (dare I say cute??
) vent rib barrel might make it more enjoyable for plinking. Ditto having some sights, as I've found that even my standard NAA revolvers are capable of more practical accuracy (like for plinking) than some people might suspect.
I thought about the new Sidewinder, to make it easier to manipulate for the loading process, but they want as much for them (or more) as some other companies want for "regular" revolvers.
Now that I'm retired, and have accepted that I have so many more dedicated defensive handguns in my safe than I can ever really justify owning, I find that I'm more interested in rounding out my "enjoyable/fun" niche. If they can also serve some supplementary practical role? So much the better. For me, this more or less means SA revolvers, including the NAA (which some folks like to refer to as novelty firearms or men's "pocket jewelry").
I'd not mind replacing that Ruger Bearcat which got traded off and left a hole in the collection many, many years ago, with a Bearcat Shop Keeper model, or even a .357 or .44 Sheriff's Model.
