Yep it’s a 1006 with the adjustable rear sight. I bought it for $400 about 5 years ago. I have the original hair dryer grip for it as well as the Hogue on it in the pic.
Alliant shows 1250fps being no problem with a 180 and PowerPistol.
Great Hog Hunting Pistol ! I put a Hogue grip on mine too. Hated the factory grip.
Saw one sell at the LGS last year for $750.
