Product Description
MAXIMUM FIREPOWER!
We tweaked our popular 170mm "+8" extension for 40 S&W, giving you a chance to load up to TEN additional rounds! That 25+1! We've also re-profiled the interior to better accommodate the new "chisel-point" followers.
Details matter, so depending on which combination of mag tube/follower you're using, results vary between +9 and +10. This extension can be used on a 22-round magazine, but requires a special spring -- if you'd like to go that route, please say so when you order. Ships with a custom-made Wolff spring.

Great extension for Glocks
This extension work excellent on my open class Glock. I run 9 major in USPSA and my OAL is longer than standard 9mm so I went with the .40 cal extension. Worked excellent without any modification.
