Well, the gears are actually just stuck there, and do not contribute the mechanisms anyway, I agree with the handle arch, I never seem to be able to pull that off.
About the idea not being executed well, how should do you think I should execute it?
if the gears are just there for aesthetic at least make them look good.
right now they just look out of place and odd.
and as for execution, It doesn't look like it has anything to do with friction or anything of he sort.
someone better at weapon making can explain that better I guess
the gradients are off in most places, making it look odd and filters never really have any place on weapons.
it just serves to make the weapon look odd, unless its some kind of futuristic weapon type deal, but that's not exactly what this is entirely
