My 870 police suffered a degrading moment when the stock actually cracked. What to do, I have three other stocks laying around but I decided to try something new. I acquired a Mesa adapter, Houge grip, and a Magpull CTR. I took it to the range with some three inch magnums to see how those worked, awful hard on the shoulder. Results of three shot groups were a little high, my fault, but they patterned well.
Before and after plus a target.
