I’ve been waiting for the TH10 also. My guess is that unlike the TH45 which is nearly identical to the TH9 and TH40, the 10 has undergone a redesign to beef it up a bit to handle the cartridge. I’ve heard the 10 doesn’t have a de-cocker like the others which is another indicator that it’s not the exact same pistol design. In the mean time I picked up a TH45 to tide me over.
