There is something about those super fly weight 22 snubbies that make them special.

Sidney,

That is an AWESOME 1911!!!!!!!!!!!!!

Pappy,
I have a feeling that S&W could very well fit the piece with a magnum cylinder but just won't do it so you would have to buy another piece.

From what I understand,the manufacturers make the barrels to 22 magnum specs (reduce inventory). There shouldn't be any problem in chambering a 22 LR cylinder to magnum

Just my opinion.
