I'm not sure where you can get full length guide rods anymore. Mike Sardinha (Msardi) made a batch of them, but has since sold his 97B. They were full-length stainless and very nice. I was lucky enough to get one early. There are probably some other members who have made them. Several members have used a Stanley door hinge pin (4", I believe) with apparently excellent results (search for the posts on how to make your own). I think somebody here put an adjustable sight on a 97B - maybe J.R. Farrar. I have never heard of anyone using a polymer slide stop or buffer on a 97B, but you may decide to move up to a 16 or 18# Wolff recoil spring after shooting the gun some. If you reload and shoot pretty mild stuff, you may not need the heaver recoil spring (or a full length guide rod). Many of us switched to the FLGR because we went to heaver recoil springs that would not work well with the stock rod. The 97B is a very good pistol, but be sure you handle one before buying it - some people find the grip (and DA trigger reach) to be more than they can comfortably use. Good luck.
