paul105 - great looking guns! That FA 97 is a great packing pistol! I've handled a couple of longer barreled FA97's (one had a nice octagonal barrel) and they are definitely handy, well-balanced guns.
Here's a picture of my current lightweight, single action handgun (.45 cal)...
It's not a Ruger and it's not a sixgun, but it's lightweight, reliable, accurate and a joy to carry. I bought it cheap at a local gunshop. the previous owner had installed a hideous looking oversized, tactical slide release lever on it, and had done some kind of pitiful attempt at adjusting the trigger pull by messing with the sear spring.
I replaced the "tactial" slide release with an Ed Brown, blued hard core lever, and then adjusted the sear spring and the gun now works and shoots like a charm.
I still haven't ruled out a S&W 329PD, but I'm going to start looking to see if I can find a used Ruger Montado or New Vaq locally for a lightweight revolver build.
