Ruger SP 101
Smith J-frame
Smith Model 13
Colt Detective Special
Charter .44 Special
I agree with the SP101. This one fits my hands amazingly well, is so very shoot-able, and is a tough little weapon. I have several of them, 2.25”, 3”, and 4”. All are chambered .357, except that the 4” is .32 H&R.
I find it interesting that “J-Frame” is listed, as it is a frame size, rather than one model, and many have been made that are not snub-length. If minimal grips are installed, to optimize shoot-ability, a J-Frame is a bit small, for me, and since my early forties, it has been somewhat painful to shoot .38 ammo though Airweight J-Frames, and torture to shoot the Airlites with my gimpier right hand. A .32 J-Frame, made of solid stainless steel, is now, in my early sixties, more my cup of tea, but an SP101 is my more-usual minimum for actual carry.
Regarding the Model 13, I have not yet had the pleasure of owning one, but do have two of the Model 64, the stainless counterpart, chambered .38 Special, though mine have the tapered 2” barrels. One is a regular carry gun.
I have owned a couple of Colt Detective Specials, at different times, long ago, but let them get away from me.
I briefly owned a .44 Special Charger Arms Bulldog, long ago. I traded it away, before I got around to shooting it, if I remember correctly.
