"DECAL Grip's (rubber) FGR (Finger Grip and Rail) are intended for use with the Glock FGR series pistol and recognized by many Glock shooters as the superior choice for Glock handgun grip control. Glock lower receivers are manufactured from polymer and tend to get slippery when wet or used with sweaty hands. This condition will severely affect your grip and accuracy. Decal Grip's are specially designed for each model Glock. The pre-cut textured adhesive strips provide you with a positive grip surface that works wet, dry, hot or cold. They are exceedingly durable and will not shift, split or tear. Rubber texture grips are 1/32 inch thick. Easily removed or replaced, simply peel and stick. Fits Glock model 26,27,33 "
