If you are a good judge of condition, you should be fine going with a used gun if you’re so inclined. I would not be afraid to buy either one. I believe odds favor the new production guns being a bit more accurate, but I’d think it would be splitting hairs.

The new guns are nice - but pricey. On the used market, I’d say look carefully and if you’re satisfied with the gun AND price, don’t worry.

If you intend to mount an optic, I’d definitely buy the new model that has an integral rail, or drilled & tapped, if you don’t care for the rail-model. I’m a bit interested in that particular gun. Cheapest I’ve seen a used rail-model in my neck of the woods was $1250, in like-new condition. I’m sure the price could have been negotiated a bit.

Either way, new or used, I think picking the right barrel is far more important. Everyone has their opinion on which length is best.
