I'm not sure about the protecter. I think the only difference betwen the Pump & the protector is barrel lenght. If that is the case, yes! I was told by a couple of "gun" guys that everything but the barel would fit. The only difference in the Pardner Pump barrel is the clip the mounts to the magazine. I would call or email H&R & ask if that was the only difference! How long have you had yours? I'm in the middle of researching them myself. I may buy one next week end at a gun show if I can find one at the right price! Please let me know what you find out! Good luck!
