It really depends on how much you handle the gun. If you drifire daily with it it may last a month, if it’s not handled a lot obviously it will last longer. You really don’t need a ton on your grip to help and it’s not permanent so it’s very easy to replace. It’s basically like tapping a baseball bat, if you’ve ever done that. Howie’s is basically the exact same thing but it’s not like Goon is charging a premium for their tape. I bought some just to play with and ended up really liking it so it’s on all my pistols. It’s cheap enough to try and it doesn’t do anything permanent to your weapon so what do you have to loose.
