R.I.P.
To be brutally honest they can be ammo sensitive. They tend to like target ammo only. If my memory serves me, CCI ammo is the preference. I have it listed in my notes at the shop so Ill look it up next week when Im back and let you know what ammo in particular.
Its not that it wont shoot accurately, its that they just wont run reliably with certain brands. They are far from fragile though.
I have seen ALOT of complaints from 41 owners about this and we know the guy at S&W whos sole responsibility is Model 41's. He gives us the straight scoop and it comes down to ammo selection. You have to be willing to use what they tell you.
All I shoot out of mine is CCI standard Velocity. I do not run the high velocity wall-mart bulk ammo .
I think I even changed the spring years ago. So strictly target ammo for me.

The M41 isn't a general purpose/sporting type handgun, it's designed strictly as a target/match gun and alot of match guns, especially rimfire, can be VERY ammo sensitive. Good quality match grade ammo of standard/target velocity should be used for best results in the immediate and long run. If S&W recommends CCI target/match, then run it. I've used in mine, the Winchester .22lr pistol MKIII match grade ammo way back in my National Match days. If one wants to run cheap Wally crap through their guns, get a Buckmark or Ruger to run it in, as they seem to like most types of ammo.
