I own an ancient M-41 with a 7-1/2 in. barrel, ray gun compensator and cocking indicator. I pretty much concur with all the above comments with these observations based on my experience with one pistol. The safety is so difficult to manipulate that it is near useless, which I think S&W intended for a target pistol. Mine hasn't been cycled in years. Reliability is near perfect with higher intensity ammunition, but as soon as the mid-range target stuff goes in it fails to eject, feed everything. Why? The chamber is stupid tight for match accuracy as are many old S&W .22 LR chambers, i.e. M-17's. In a blowback action the recoil energy has to pry the empty from the chamber, compress the recoil spring, flip the empty out, cock the hammer and push a new round in. If the chamber is sticky, nothing will work. I'm sure that a careful reaming would help the problem with the risk of hurting accuracy. For me a bristle brush every 200 rounds or so solves the problem, not an issue on a target gun.
