See our guide for modifying your standard mag spring to run 20 rounds. Alternatively use a Nic Taylor 19C or 21C mag spring. If you aren't using the M9 Guide Rod System use our upgrade for the standard GSG 1911, one free with two or more Extension Kits!

 M9 GSG +10 Recoil Spring £16.50 In Stock
RRP £16.15, £10 when purchased with one +10+ Extension Kit or get one free spring when ordering two or more +10+ Extension Kits
The M9 Advanced Upgrade Recoil Spring (top in the photo, bottom is the standard spring for comparison) was developed to provide the additional slide energy required to reliably chamber rounds in magazines extended beyond 16 rounds in an otherwise standard GSG 1911 pistol. 

Stainless Guide Rod System £155.00 In  Stock
A full-size, full-length stainless steel guide rod kit incorporating the stainless guide rod  with our unique adjustable vertical barrel alignment technology, custom recoil spring, poly buffers and release button/bush, blueprinting  the slide system and providing significant improvements in both grouping and cycling. We recommend this as the third step in upgrading your GSG (after a Series 80 Delete and M9 Breech Block Modification).

The Accurizer Kit gives tight, repeatable alignment of the slide to the barrel when in battery and increased Barrel to Bushing clearance for 95%+ of the cycle, reducing friction improving cycling and hugely improving accuracy with slide-mounted sights, it is highly recommended to fit the guide rod kit before the Accurizer Kit to provide the required barrel alignment and springing for optimal Accurizer Kit performance.

For fast smooth mag changes without switching focus away from the course of fire, the M9 magwell comes threaded M6 to accept the extension rod of your choice, fitting is simple and the magwell is completely stable and secure unlike the standard bracket.
