Bought these springs for the 3/4 mag extenders and they worked perfectly.
If you don't use a longer spring, the stock Glock OEM spring could and probably will fail you at some point (hopefully not when you really need reliablity). This spring has been very positive when feeding rounds through my magazine with zero issues with my TT 2/3 mag extension. My product came with 2 extra springs and they were easy to install (Though the longer spring required a little more downward force to slide the mag extension on due to the spring length to the Glock OEM magazine size).
This product is a perfect upgrade/replacement. Great tension. No issues.
