I started off with a .177 version but it was never going to be enough. Soon added a genuine shoulder stock and correct foresight. Then when I realised I would have to re zero when I took the stock off, I bought a .22 with silver finish. Finally a .20 with Hogue grips was sourced. Wouldn't part with any of them. The HW45 is the best general purpose air pistol out there in my view, from a user's perspective.
