Your going to hate yourself and me in the morning. That is either the Taurus model 44 in .44 magnum or the 444 Ti, which is the light weight titanium version of the 44. Since the picture is fuzzy by the muzzle let it be said that there should be a built in factory compensator at the muzzle. Very good condition model 44 price is $375. Good cond.:$250. Fair cond.:$200. If the gun is mechanically sound the price sounds about right. Model 44s weigh in at 53 ounces. Looks like the 6 1/2 inch barrel barreled model. 4 inchers have a solid rib and the the other barrel lengths are all vent ribbed.

Steelheart is right. A 4 incher would be a better backup gun and would clear leather better and faster. 3 inch barreled revolvers are nice if considering them for this. One caveat is a little velocity is lost and the noise increases. While .44 mags are nice and one wants as much power to stop a charge, maybe a Taurus model 66 or S&W with 7 rounds might work out. 160-180 grain hunting slugs are available in .357 magnum. Buffalo Bore Ammunition has 2 loads that would give one all the penetration one would need in .357 magnum as well as the 44 maggy.
