IMO, I would have to say it was the best decision I have ever made. Completely worth the wait for the work and the money. I have not had any issues with this build, plus it just looks sexy! It's not a Fatal 15 by any means, but I do feel that it is a quality piece of work.
Never handled a AA Glock but if you are just wanting slide cuts/lightening, cerekote, color fill, etc...maybe look at ZRTS in Noblesville. Zach did an incredible job on my G21 slide (slide cuts/serrations/milled for RMR/battleworn cerekote) and it shoots like a champ. Good prices, quick turn around and local...plus just a nice guy. IMHO
