Hi Folks ! First a short explanation... I recently bought a M&P 9mm compact for my wife .... She likes the gun and can cycle the slide, so that's good. Since it's the shorter barrel , it does have some muzzle flip that doesn't seem to offend her much. BUT...... to make practice as pleasant as possible..... I'd like to find a weight that could be attached on the light rail. I'm almost sure that I have seen them in the past but I certainly can't find anything like it now... Does anyone have the name of a product or suggestions ??? Thanks ! mike Wanna kill these ads? We can help!
