Ok, so using the gloves allow you to use a Basic Weapon single handedly with out the -20 mod.
They're considered Rare (as per Errata 3.0), and they're really quite cheap.
So, provided a character can Find them and is willing to pay over the odds for a pair of custom made and can spare the time for them to be made, should they be allowed to buy them knowing full well that under their bunk is a pair of Autoguns waiting to be used together...
Would you allow it?
Part of me wants to say "Hell no! that way lies Twinkery that is hellish and on par with DnD at its worst..." but another part of me wants to say "ok, so they Were using two Autopistols, they got the Guns and the Gloves and paid a LOT of xp for the talents that pretty much mean theres not much in the way of Negative mods. And dear gods the Fun to be had with all that damage...."
I'm Torn.
