I and the SW Factory can not figure out why my M 41 will not function on any Federal ammo (any kind) Heck the shot case stays in the chamber. Itt will not extract at all. The listed MV is actually higher than the CCI SV Target.
Sent it back twice, it runs on CCI so they are done with it.
The gun was designed around CCI Green Tag but I am not trying to find or pay for that.
I just got the reduced power springs from Wolff so gonna try those with some other SV ammo
