Like the others have said already you have a great shooting revolver there if everything is okay. Those early 625’s have a great reputation in competition and generally support pricing like you paid. However your gun does have one problem that I can see but it’s easily corrected. Those Pachmayr grips use a screw that interferes with the mainspring. It actually contacts the spring on cocking and in the DA mode creates a noticeable knuckle or hard spot. Swap out the grips and problem solved — S&W did just that shortly after your gun was made.
