I read on here that the HW45 Star has three sizes of grip available and is supplied as standard with the smallest one.

Sure enough, a call to a local dealer confirmed that, and that he knew the price of the standard grip to be abt £165. It would be reasonable to expect the other two would be similar if ordered. No way.

I have large hands but will not de-value my 45 Star by wood-working the standard grip.

Instead, I've been shooting it left-handed - my left hand is smaller than my right. Turns out I can shoot just as badly left-handed as right-handed. Left handed is just as comfortable to shoot with. Surprised me.

If you have an ambidextrous pistol, or even if not, then there's your next session's shooting challenge!
