It may be better for the OP to sell it for parts. Stock complete G34 uppers go for anywhere from $300 to $450. Other people like the trigger bar with the smooth trigger for G19 and G26 guns. The frame parts can go to someone building a Polymer 80. It is more of a hassle, but you will get more.
I like professionally stippled Glocks and have more than a few. I usually purchase for a fraction of the original price of the work. I have bought frames stippled by big names for less than $150 shipped to my FFL, including a new Cold Bore Customs G17.3 frame cut to G26 factory length with the magwell beveled, a speedwell added, and Carry texture stippling. I added a Vickers FDE G17.3 upper with a Gadget SCD, and my armorer friend added all of the frame internals. It is now my primary Glock carry pistol. I call it a G26XL. My total outlay was right at $550 or what a stock Glock with a Gadget would cost.
