I guess someone should add the obvious, namely that the purchase price is the minor consideration. That is the unfortunate truth for this potentially excellent product. I say potentially because unless you are extremely lucky, what you will receive is an unfinished project gun which will demand countless hours of your time, or a gunsmith's time, to bring it to the level of a smooth, reliable and enjoyable firearm. I've done it now with 3 Ruger revolvers and I won't do it again. I have about 20 hours a piece on my SP101's and the same on my GP100. What's the time worth to you? One more consideration. If you happen to screw up the hammer or trigger, all your careful work is lost because these parts aren't available. Or, more correctly, they are available of you send the gun to Ruger, but they will re-install new parts fresh out of the casting machine and you will be starting all over. Just some extra thoughts on the saving of a few bucks.
