The Reason Gen 3 And Gen 4 Slides Won’t Work On Gen 5 Glocks
This video explains why Glock Gen 3 and Gen 4 slides are not compatible with Gen 5 Glock frames, specifically the Glock 26. The primary reason is the Gen 5's ambidextrous slide stop, which requires bilateral cuts on the slide that are absent on older generations. This technical insight is provided by SPN Firearms, demonstrating expertise in Glock platform mechanics.
