I have this figure (not so well painted…) and I just had a look at it. Yes the hands are a bit too large especially the part under the thumb behind the pistol, however if you look from different directions it’s not so obvious and also the rolled sleeve adds to this impression. I must say I’m really not troubled with this. For some contexts I use almost only Copplestone’s and Bob Murch’s figures, for some other games Paul Hicks’ and some others, and I avoid to mix them.
Slightly alarmed to hear that Copplestone and Hicks might not mix well. I have several projects in which I’m intending to use figures by both sculptors. I own figures by both (none yet painted in the case of Hicks) but don’t think I’ve ever bothered comparing them side-by-side.
