guy, just bought a model 909, 9mm. seems to have been fired very very little. the gun has a plastic recoil guide rod, and the tip,(the end that fits into the frame) is "spring loaded". i'm told this is the same gun as the 3904/3906. i'd like to get a steel recoil guide rod like the ones on the 3904/3906 but i'm not sure if it is the same thing. haven't talked to s&w yet. thought i'd post here to see if anyone has any ideas.
