Jgulbs pointed me towards an interesting article http://militarytimes.com/blogs/gearscout/2012/01/01/glock-setup-tips/, How To Make Your Stock Glock Rock. Seems like a good start before I start buying a bunch of aftermarket "upgrades."
Any tips/thoughts from armorers? What are my chances of doing more harm than good by busing out the dremel and polish? What is the best way to tune up my Glocks while keeping them dead nuts reliable?
..as long as I have your attention, thoughts on aftermarket sights? I have my eyes on some warren tacicals.
