I have an old Springfield Armory P9, basically a small-frame Tanfoglio, standard length slide. I just got a Henning conefit guide rod and buffers. When I went to install them I see now that there is no bevel on my frame where the GR sits, thus the cone fit does not sit flush with the frame (the GR rests on the cone part). The pictures on the vendor site show the cone nesting in a bevel on the frame so I guess this is a change in the Tanfoglio design post 1994.
Has anyone else ever encountered this with their clone? How did you resolve it?
TIA
