I have the chance to pick up a used 5906 with a few mags for a good deal (around 275 out the door). I know there are some 3rd gen Smith aficionados on here, and wondered if there would be anything to look for as far as red flags? I have been looking around and it appears that I can get replacement springs still, but what about other parts (firing pins/trigger bars/etc.). This will be mostly a gun to shoot some local matches, and after getting some rounds thorough it I will probably end up buying a holster to carry on occasion. Thanks much in advance for the help.
