I have both, the SP101 (4.2" barrel and fully adj. sights) and the Bearcat (both fixed and adj.).
When checking the chickens, having a keen eye for feral cats or egg gobbling snakes, the little Bearcat is my mainstay. I refer to it as my "Chicken Checkin'" gun. I love its light weight and delicate lines (something missing from most current production guns).
On the other hand, the SP101 offers more heft and a couple of extra shots. Two coyote have fallen to the SP, as well as, numerous other vermin. No flames on the inadequacy of the rimfire for such a critter, please. As referenced to Dizzy Dean "It ain't bragging if you can do it."
Now for those who feel the 22LR inadequate..., please join me in soliciting Ruger and Lipsey's to, again, join forces and produce something we can all agree to need..., a stainless SP chambered for 22 magnum! Hopefully having a 6 shot cylinder, 4 or 5 inch barrel with adj. sights, I think it would prove to be a winner for many applications.
