You are correct about the noise and flash. Back when the 22LR became scarce, the only 22 ammo on the shelves was 22 Magnum, so I started buying and have accumulated quite a stash. So when I get the chance to get the 351C to the range, I'm going to make it a 22mag outing with the 650, 651, and the Ruger 22 single six convertible.
