Initial review on @ShieldArms +5 mag extension for Glock 17 + some thoughts on testing your equipment/thesis. TL;DR - time will tell how these mag extensions hold up, but for now 10/10 as far as I’m concerned - the gen 6 Glock 17 is a phenomenal gun, this one has 3k + rounds on it thus far. No issues - the @TimneyTriggers pro competition trigger for Gen 6 Glocks is A+ in performance and is definitely making a difference in my performance - the Holosun 507 Competiton is a tough optic. It can take a beating, hold zero, and beg for more. - Competition shooting is not only useful for improving your skills, but it’s a great way to test your equipment. All the whiz bang stuff in the world is great until it doesn’t perform when you need it to. - Go train.
