Johnw: My local gun shop has a lightly used MK-III 22/45 heavy barrel for sale at $300.00 so I would assume that a NIB pistol would be a good buy at $299.00.
I just buy these Ruger MK-I's, MK-II's, MK-III's and MK-IV's when they come along and I have the money.
They hold their value and are super fun guns.
Enough for me.
Best of luck to you if you decide to go for it - I wish I could be more help on your price check inquiry.
Hold into the wind
