I am a huge fan of Pearce Grip Extensions, this extension is for the Springfield Armory Hellcat 10rd/Taurus GX4 11rd magazines, will give you 1 additional round, and will give you that much needed "pinky" extension. You will get a much better grip using this extended floor plate at a minimal cost...

From the manufacturer:

This unit replaces the magazine base plate on the Springfield Armory HELLCAT and HELLCAT PRO. This extension adds one round capacity to the magazine and adds approximately 3/4" inch additional gripping surface. It also incorporates a texture similar to the frame. This product utilizes the patented PearceLock attachment mechanism.(US 10,996,010 B2)

Works on 13 round magazines, but users will lose a round of capacity on these magazines because they are equipped with factory +2 extensions. You will however gain a better grip due to the parts enhanced ergonomics.

***Will not work on factory 10 round HELLCAT PRO magazines with extended plastic spacers.

***Also fits Taurus GX4 and GX4XL
