Upgraded 170mm Glock Extensions — Including .40-cal!

9mm optimized +12, .40 optimized +10, aluminum .40 +10 (custom order).

Many of you know our 170mm Glock extension under it’s old name — the “plus eight”. We’ve upgraded the old “plus eight” many times over the years, and this month, we’re introducing a .40 S&W optimized version. Thanks to some upgrades, today’s model is a +10 — and takes its place alongside a 9mm-optimized +12. No matter what name you use to describe them, ours have been the go-to “big stick” extensions for Glock jockeys for more than 20 years.

The new variants also include the quick-release “Chludenski cut” locking plate — making dis-assembly and cleaning simple.
