Why Disassemble and Reassemble a Glock 29 Completely?

I’ve torn down dozens of Glocks over the years as a gunsmith—and if there’s one thing I’ve learned, it’s this: 10mm runs hot and hard.

Full disassembly isn’t just about cleaning—it’s about spotting cracked springs, worn cups, or gunked-up strikers that compromise function. You don’t know what you don’t know until you strip it bare.
