The M41 was designed around SV ammunition and that's all I've ever shot in mine for close to 30 years.
I can see a brick or 2 of mini mags to "run in" a new M41, much like breaking in a new 1911 and getting the internals to mate to one another. But, a steady diet just seems to go against the basic design of the pistol, beating it up for no good reason. That's what Rugers are for. ;-)
But, there is SV and there is SV. Even back in the early 90s (my 41 is 1990 vintage), with the 'black bullet' CCI SV in the 50rnd boxes, function was just Ok, but nothing to write home about. Accuracy was decent.
Then, a friend got me to try Wolf MT (rebranded SK Standard Plus). I had just figured it was Russian garbage till he clued me in. Everything seemed to improve by an order of magnitude, both function and accuracy, like night and day.
For the longest time I had just chalked it up to SK/Laupa's better QC, which, while true, I had ignored the lube, that greasy 'Wolf snot' that SK used. Lube is lube, right? Well, apparently not as my M41 shows a decided preference for the 'greasy kids stuff' over the dry wax lube like on CCI SV.
Ended up buying 2 cases of the Wolf back when and 50cal ammo cans to store it in. Use it in all my .22s and they all seem to run better and are more accurate with it.
