Quick deliverance from DAA as all ways .. When this spring is to be used with the Arredondo 9mm teflon follower (can not fit any other spring)it is necessary to use the Arredondo spacer aswell. The spring is to wide, front to back to be used with an STI spacer or the metal spacers in a STI 140 mm...

Just used it over the weekend after tuning my mags. Excellent - no feeding problem when loaded to max capacity.

The best possible spring to use in your magazines, custom made by Wolff springs for Arredondo design. This spring is longer and stronger than the originals supplied with most magazines. It is designed specifically for 170mm magazines. Will clip on to Arredondo followers, but can be easily fitted to work with most other followers as well. 
Will outlast any other spring you have ever used! 
Specify gun type and caliber when ordering.
