Earlier this year my father bought a new Smith & Wesson Model 41. It came with two magazines and he bought two more.

Now he is an experienced shooter and knows what he is doing. But with some of the magazines he gets jams, failure to feeds, stove piping, etc. The other magazines work fine shot after shot after shot.

We talked to a gunsmith and he said that used to be a problem with some older models, and the solution was to disassemble the magazine, insert a 1/32" shim in the bottom, and you'd be good to go. But the magazines produced by S&W for that gun today are sealed and you can't work on them.

Does any company make custom mags for the Model 41, like Wilson Combat does for 1911s? Or is S&W the only source for magazines?
