M41SW

Why would anyone put a 8 lb. spring in a M 41?

Need some info. Can someone explain to me why a M 41 would need a 8 lb. spring.. I know factory is 71/2 lbs. Thanks in advance.

I've been shooting USPSA for years " CRO "..I shoot a Glock 35 Open ,with a doctor sight. Just a great set-up.. I reload 40 s&w and use Montana Gold 180gr JHP. Couldn't ask for anything better for year round shooting in Florida.

I've been shooting USPSA for years. I'm also a Chief Range Officer.. I shoot Glocks, and zero in at 25 Yards.. You have to get to know your gun thru practise.. Then just hold your sight picture up or down depending on the distance..USPSA shooting is very different from Bullseye shooting..Bullseye you only shoot 25 and 50 yards.. USPSA you are on the go, and you shoot from 3 yards out to 50 yards. Cardboard and steel targets..
