I know I'm gonna get flamed with all the "you just don't understand about building your own Glock" blab. I understand that one can achieve a sense of accomplishment in building a firearm. I know quite a few guys that have built an AR and they end up saving at least $100 if not more. I would be all in favor of building my own Glock if it was actually cheaper. I can get a lightly used to LNIB Glock 17 or 19 off Armslist in my area for around $475. For me to build a Glock 17 or 19, it would cost me around $700. Sorry not paying a premium for the privilege of building a Glock.
