Having used your 2 round extensions on multiple mags for two Glocks, a G26 9mm and G29 10mm, this shooter can attest, they’re fine reliable products. With the extensions, pistols that can charitably be categorized as having the worst factory grip in all pistoldom, can now be held with a proper hold, either one or two handed. Pinky fingers no longer dangling about the ether. The texture and shape match and blend seamlessly. The fact that the weapons are now 12 shooters is an added bonus. Your grip plugs, though not as essential as mag extensions in this case, really help finish off the guns. These Pearce accessories have helped me configure two very serviceable everyday carry concealable pistols. Joe McGuire
