First off, don't believe that you will get a revolver that was "only shot once a year for qualification..." While I suppose that is possible, it's quite unlikely. If there's one with THAT little amount of wear, I'd bet a Bud's employee snags it.
Expect that if you have only ever bought new guns, or used guns that have been barely touched, this one has a decent chance of arriving with as much (or FAR more) exterior wear, possible neglect or even a slight bit of abuse.
However, when you consider the price, and much more to the point-- when you take it out and shoot it, you'll quickly get over it's worn exterior.
It is also worth noting that Smith & Wesson does -NOT- warranty formerly issued firearms, and they will know simply by serial number that it is. And I only post this because it's true, not because I have any belief that you'll need their crack team to work on your purchase -- these revolvers are
phenomenal and I doubt you'll have even a hint of a problem.
I only own a single formerly issued Model 10 and when I first got a hold of it, I did so with an evil plan to just
beat the ever-loving tar out of it and see how far I could push it and abuse it so that I could see how it would respond. But I absolutely flushed that idea down the toilet after a
fantastic range session with it and it truly, absolutely is one of my favorite shooters, even if it just looks like it's been treated poorly.
IMO, this is a VERY low-risk, high-reward purchase. And we have a routine around here tossing out over-used quips and corny lines. But in this case...
...since you admittedly don't own a .38 Special revolver, buying this one at $325 could be a REAL gateway and you may seriously find yourself chasing revolvers. Just don't forget to come back to this thread, quote me, and tell me how many different ways I was absolutely correct!
