Question: will this fit on the 20ga 500?
Document: What a great addition to my shotgun. Great hold and the rubber grooves fit my fingers perfectly. Worth the $$
The grip fit perfectly and is a nice change from the standard stock. My only concern is the need for a socket extension to unscrew the bolt that held the stock in place.
I cud fire 100 rounds through my mossberg 500 breacher barrel blackwater edition, and have no hand or wrist pain at all. The cushion at the webbing of the hand is in the perfect spot. Grip is perfect for my hand, has a great feel, and makes you feel like u have a more secure overall handle on the weapon. Def recommend.
Very happy with the fit a feel of this grip. Fit was really tight an you have to make sure everything lines up, but it is nice and tight. Works real well on my maverick 88.Comofortable in the hand.
This grip is sweet, nice and grippy in the fingers. The sling mount on the bottom is a nice extra touch. handels the 3inch and even the 3 1/2 inch 00 buck shells from my mossberg 535. perfect fit! !
very nice soft rubber grip. very worth the $, too bad theres nothing on the back to add a stock and tube later on
There's no problem mounting this grip after you get the stock offand it feels great in the hip position for shooting. Better do some wrist exercisesthough cause it hits you there quite violently, and I'm only using target loads.Since I am no longer using the sights, I've mounted a laser sight. Hope I never have to use it in anger!Hope for Peace, G. Ball
Nice, oversized grip. Super comfortable, easy to install, and seems to only get easier to grip as you handle it. Really helps reduce some grip fatigue that I have squeezing smaller grips
It's firm, holds fast, easy installation and took my Shotty to a whole new level. I renamed her from "The Deltoid Buster" to "The Key to The City." Great product. It looks like it is. I'd buy it again if the need comes up.
It took no time installing and the directions were on point and easy to read, and  the shotgun looks great...
Answer: no
