i asked about recoil pads recently for my pardner pump 12 gauge, i have measured my stock and found that i need the small size. when installing a pachmayr, limbsaver, or allen slip on pad will it work if i take my old pad off? i'm not a tall or long armed person and leaving my old one on will make a length of pull thats not right. so my question is if i take my old pad off will the slip on still work as in holding on and not slipping? thanks
