There are the "regular" Tisas "US Army" and "Service" models, and then there are the "blems" which are being sold at the cut-rate prices you're seeing now. Apparently, the Parkerizing isn't "taking" the same on various slides and frames, causing some appearance blemishes, which is why the prices on some of these pistols are so low. They are clearing out whatever demand will allow right now, and demand is pretty high.
Tisas also has "Duty" and "Carry" versions in stainless and Cerakoate, with better sights, beavertails, some with rails and some without rails, that cost a fair amount more.
