X3N0Wolf @TXR4521 No offence taken at all my friend =) Quite the opposite actually, it's nice to have someone interested in my designs. I have indeed used the original weapons as the base, and that's where the issue with the handles comes from; if you look at the stock weapons, you'll see that they're not identical, but mirror images of each other. There's a space for the thumb to fit into on one side of each, but not the other. That's easy enough to accomodate on my designs, I simply added an appropriate cavity on each side. But the more significant difference is that the handle isn't in the center, it's offset to one side slightly. You can see in this picture what happens if I have the handle in the middle; it's not flush with the outer edge of the arm, and sits proud of the inner edge. So I can't just make it wider as that would exacerbate the problem on the inner side. Some people might be fine with it like this, but I'm a perfectionist, so I was trying to make a handle that could be pegged in to one side or the other. The design concept is sound, but the imprecision of printing in WSF means the tab and slot design I've used isn't very reliable at all. If it was printed in Frosted Detail it would probably be fine though... =)
