I bought my M41 new in 1984. I bought a used second one in 1995 that dates to the original one. I am on my third case of CCI Blazer ammo. Yup, the cheap stuff. 99.99% reliable, more accurate than me, and neither gun is 'battered' from Hi Velocity ammo.
The Blazer ammo is not as hot as CCI Mini Mags. I clean my M41 at the practice range when I am done shooting before "tomorrow's" Bullseye match, then fire 1 mag of 10 rounds. When I get home, I thoroughly clean frame and slide rails, face of slide and extractor, 2 drops of oil on rails, and the gun is good to go for the match. I don't think I have had 5 alibies during a match in 30 years with my M41.
YMMV
