Was in need of a new project so I decided to put together a Glock 19 9mm using no Glock parts. Nothing against Glock. Just decided I'd like to have something a little different. I've started with a Polymer80 lower in a Cobalt color which just looks gray to me. For the upper I decided to go with a contrasting black color. I finally decided on an upper from Palmetto State Armory. I was able to catch the complete frame on sale for about 80 bucks with shipping and tax. The slide and barrel ran me about $275. It's cut for a red dot and it has suppressor height night sights. Picked up a few Magpul 15 round mag's. Only thing left is a holster and eventually an optic. Anyone have any good advice on an optic that won't break the bank?
