Good quality but fit up issues with my 870 hardwood home defense - TacStar Slimline SideSaddle Shotshell Carrier

I purchased this side saddle for my 870 hardwood home defense. The product is made from good materials and it fit up perfect. Installation was a breeze it comes with the wrenches needed to install. Once it was installed I went to rack the slide and hit hit the side saddle. It stopped the slide about an inch and a half from the open position. I was disappointing because it is a nice and plain product, but it wont work with the hardwood furniture. I would recommend it if you are going to put it on another model, but don't buy it if you have the hardwood home defense unless you don't mind doing some modification. I'm still trying to decide if I'm going to modify it or send it back.
