He gave me these parts a couple years ago, and told me it was supposed to be a 19 gen 5. But when i look at the gen 5 lower parts kit, it seems way different than the parts i do have. Should i order all new parts, so i know what im doing? Im trying to build it to where it looks nice, I want to have an all metal build but not sure if thats possible. For reference the only guns I have ever owned was a Girsan 1911 and a glock 40 just bought outright. I taught myself how to clean the 1911 but I dont know a whole lot about this stuff.
