Yep, They're not cheap but they are very good guns. The Sig Trailside is made by Hammerli....you know the Swiss firm that makes guns for Olympic shooters. It is now discontinued as Sig wanted to offer their own .22 (it's nothing like the Trailside) so the price is going up.
If you can find a Trailside 6" model with adjustable sights for under $500, buy it. I have an extra Sig Competition model with anatomical grips, forward weight and box for $675. These too come up for sale once in a while.
