There are a number of guys who own that model as well as the one referred to as the "mistake" version who complain the front sight is a bit too short. There are a couple of options, one of which is of course to pin in a new taller front blade. That however will of course ruin any collector value. The other and more simple option is to simply shoot a lighter bullet. Here is a link to a group buy for a 185 grain .44 Special bullet that should get the Shootists 44 Special on paper as well as have all sorts of other useful applications like be a dandy for Charter Bulldogs and Smith 329s and such.
