I disagree with the statement that model 41's are made to run on CCI SV.
My 1980 vintage model 41 will not run on SV, unless you put in a reduced power recoil spring. I have shot Super X HV and now CCI blazer HV since the early 1980's, never replaced a single part except recoil springs, (std S&W springs, no buffer). I shoot around 5000 rds a year thru it, it is still as accurate and dependable has it ever was.

When can I expect for the disaster to start ?
