I have a Buckmark & a very nicely done MkII. The Buckmark is the more accurate of the two, but not by much. However, when I was playing at rimfire steel shooting, I shot much better times with the Ruger.
My Buckmark is also the more ammo finicky of the two & heavily lubed ammo like Fed Auto Match would gum it up after a few mags. That said, if you wanna play the suppressor game & you don’t have a threaded Ruger, I’d give the nod to the Buckmark- threaded TacSol barrel for the Browning is fairly inexpensive compared to the Ruger, where you have to replace the entire “upper” that requires a 4473.
Wife has a Walter P22 that’s a fun little pop gun, but it doesn’t always like cheap ammo.
