Dan4147 Posted October 8, 2019 Share Posted October 8, 2019 I have read all on here and other places about the +/- of stroking. So I like to tinker, and as a guy on here known as Apolo has suggested, it might be fun. Question; it appears due to the design of the Tanfo, all that needs to be done is remove a set amount (still undecided) from the rear of the quide rod tunnel rear (where it stops on the frame during recoil). Does anyone know anything else that has to change, other than recoil spring length? Thanks. Quote Link to comment Share on other sites More sharing options...
Dan4147 Posted October 9, 2019 Author Share Posted October 9, 2019 Well. What I got from one experienced, the answer is yes. Amount varies from .250 to .350 removed (stroke length added).Then determine recoil spring weight and length to achieve flatness with no coil bind.

jcc7x7 Posted October 9, 2019 Share Posted October 9, 2019 I had one with .250, used stock 2 springs if I remember correctly. Don't think it made a lot of difference. Fwiw Quote Link to comment Share on other sites More sharing options...
MikeBurgess Posted October 9, 2019 Share Posted October 9, 2019 Yes, just remove material from the back of the tunnel nothing else but check for coil bind is necessary. I would make sure the cut has a radius where it meets the slide so I would not induce a stress riser. Quote Link to comment Share on other sites More sharing options...

Fwiw That was my old gun and yes i stroked it by .250. i used stock 2 springs and they had to be cut so they didnt bind. I also dont think it made much of a difference myself.
