Good but not 100% - Phoenix Technology KickLite Shotgun Stock Glass Filled for Mossberg

I purchased this for a new mossberg 500. It fit and went on easy. I put 100 rounds through it and no issues in reliability. The recoil is average to moderate, however... unfortunately this hurt the base of my thumb, and I was wearing small gloves as it was cold. I haven't had this issue before, but if I didnt tighten my grip all the way and kept my thumb below the natural placement it didn't hurt as much. So it could use some rubber padding there to make it fun to shoot. Also, as all other pistol grips do, you have to unshielded the gun to press the sl8de release.
