We have a Ruger LCR22 and a Beretta 21a Bobcat.
They are both fun to shoot.
The LCR shots everything I put in it.
The 21a is really fussy. It loves the CCI stingers, Mini Mags, and Win. bulk 333.
I have two 21's and I can say ditto (most everybody will report the same). Great little BUG or just fun little-mouse gun.
The LCR has the advantage of not being subject to possible cycling issues as opposed to the semi (only worry there would be a bad primer).
