It has a 45 grain bullet at 835 fps. It would cycle my TX22 fairly reliably, probably moreso with a suppressor attached.
The TX22 is maybe a little bigger than the M-71, but holds 16 rounds in the magazine.
It is about the same weight at the M-71 without the fake suppressor, 17 ounces.
I’ve been wanting to get me one of those Taurus .22s:)
