I agree to put it through the revolver check out at the top of the Revolver forum. Any new or used revolver should go through it. If it passes, it should be fine.
The Taurus 83 seems to be an adjustable sight version of the 82. It is a basic, but solid, medium frame .38spl along the lines of the S&W M15/67 (adjustable sight versions of the S&W M10/64). It should make a fine gun, though if it is an older Taurus the trigger may not be great. My first handgun was a Taurus 82, it always went bang and was as accurate as a new shooter could hope to be- selling it was a huge mistake (I didn't think I'd own many handguns and I bought a medium frame .357mag so I sold it thinking I didn't "need" it).
The price seems decent.
