I just finished second revolver at the IDPA Nationals shooting a 3inch Model 10 in 38 special. I like the newer short action K-frame S&W's. Make sure your ammo makes the power factor. You have to load near top loads from the reloading manuals for 38 special to make it. Use round nose bullets for easy reloading. Good luck. Revolvers are fun.
