I am about to commit the taboo and build a Match USP in .40sw. I have the trigger, and barrel figured out. The issue at hand is finding a factory compensatory that isn't $800. There are some unengraved look alikes on eBay, but I want it engraved to be identical. I found an airsoft company that makes one out of 1066 aluminum for $98. Has anyone tried using anything like this? It looks to be a exact copy of the factory original, but $700 less.
