Has anyone changed out the mainspring on the M9 22? I read somewhere that someone had put a D spring in the 22 version. So I got a 17lb one for the centerfire version but the spring is not the right diameter and will not fit over the hammer strut. So I am wondering if someone has done it what spring did they use or did they mod the hammer strut |
