She is in her 70's so she has small week hands. She shot both my 9mm Canik 55 TP9 and Taurus Pt111 9mm. They both seemed to jump around a bit.
MIL special.
LCR rimfire is not a good choice for weak hands. The hard trigger pull combined with weak fingers will make it hard to shoot accurately.
The little Beretta Tomcats are soft shooters from what I have been told. With the tip up barrel it also means no racking of the slide.
