$100! That's a bargain for sure. There is one just like it on GB right now at $300 and I figure it will bring around $400. These are great pistols. You've got a good example in the 4" with adjustable sights and some of the nicer wood grips I've seen on one. Mags are readily available as are replacement parts, though in that condition I doubt you'll be needing any anytime soon (maybe pick up an extra firing pin). These pistols are easy to adapt to suppressors as well by changing out the barrel nut. Mine have all been extremely reliable with most ammo. Shoot it and enjoy.
