Obligatory exterior and slide Gen5 Glock 19 comparison VS my heavy used Gen3 and Gen4 19's. Both have random mods and tens of thousands of rounds through them both, the Gen4 more than the Gen3. Visual Comparison. FDE Gen3, aftermarket magwell on the Gen4, Stock Gen5, never fired.
Business end:
Slide:
Barrel: Gen4 (L) / Gen5 (R)
Glock 19 lower parts description and visual walk-through coming tomorrow.
Review of Ameriglo BOLD / FBI sights coming soon.
