Two sets of pearce grip extensions. The xl is just a big bigger but makes a better difference if you havea bigger hand. Perfect fit for my pinky finger.

The hekagura glock tool kit includes that plus a couple of other things that come in handy if you want to be your own glock armorer. It matches the rest of the grip. Great product.

The 26 is fine to shoot with the flush fit mags, but the 27 almost requires these. Looks nice on my gen 3 g26. Fit my 26 perfectly without adding much length on any print ability.

The motion is kinda like cracking a beer open when using the tool, lol. Goes on easily with a glock mag tool and a c-clamp.

Pearce grips are not nearly as good as the pearce grips i have on my glock 42. I will probably need to remove all 3 of these from my mags if i plan on going shooting.

The page asks me to choose which of several models i want to order, but with very sketchy 2-3 word descriptions, no photo, and no reference to the manufacturer's part number. The picture and description are very misleading.
