Awesome
I uses use these in my hk vp9 mags with +5 mag extensions from hkparts and they last thousands of rounds still locking the slide back.
Designed exclusively to work with TTI base pads. Each coil compresses and stacks into the neighboring coil to provide the highest capacity available in your magazines.
*Also compatible with PPQ +5/6 Magazine Extensions.

My springs needed replacing, ordered Brownell's springs, then could only load 19rds. Replaced with the correct springs from TTI, 22-23 rds. Don't settle for others, use TTI springs with your TTI basepads.
very pleased,works excellent with mag extension.
