I was hot on it until my spring company was sold off and my inside guy let go! I receintly tried to re-connect with the company and they wouldn't even talk to me about a small run, not to mention test runs until it would be correct? I've found the Wolfe springs to be satisfactory, although I still prefer original mauser WW2 for the 9mm. The .30 Luger are a crap shoot of used springs I can find here or there... One thing I always do with a new spring is mount it in a drill press and compress it fully a few times, this sets the spring and reduces its free length about 1/5 so it is easier to install... Best to all,til...lat'r....GT..
