They told me 45-60 days. In fact I ordered a long barrel version online, and they cancelled it, because it was out of stock. Darrin emailed that the walnut thumbhole, and polymer thumbhole are in stock.
There is/was a 22 caliber polymer thumbhole on ebay for 950 shipped. I am sticking with 177 because I have 6 magazines, and less pellet inventory, plus the laminate should be heavier.
As a side I shot 6 magazines yesterday, and the manometer reads over 1/2 full. I can get 10 magazines on a fill, but I generally shoot 6, refill the mags, and top off the cylinder. Again that is for my adjustment of the regulator and hammer. I guess maybe I am doing 700+ fps with 8.5 grain Norma pellets. I get same hole accuracy at 10M, and a high shot count, so numbers don't matter to me. It also shoots 10.3 crossman well, and same in JSB.
