Yours looks pretty much unadulterated. How many rounds through it ? I would get you another set of springs from Gunsprings.com if it has a higher round count, which it doesn't look like it does. Your gun rails will really like BreakFree CLP or a light gun oil. With that matte finish a light coat of Vaseline heated with a hair dryer then lightly wiped off will protect the finish. Or Eezox, whichever you choose.
Don't run +P rounds in it. The barrel is too short to take full advantage. Best bet is heavy loads, maybe 230gr. Federal HST standard pressure.
I have a Officers Model and just love it.
