There are no serialized internals in a Glock That can be changed? Ok, the barrel, but that barely counts. $7-800 to make it shootable? Me thinks you need more practice, and less parts? Or a 1911.It might allow them to realize their guns should come with metal sights and not rubber dovetail protectors.
Definitely one of the mandatory upgrades for my 20. The only thing stock in mine is the actual frame itself and the metal of the slide. All the interals have been changed out that aren't serialized. It only took another 7-800 to make it a shootable gun
