I've had trouble with the Sims pads. They seem to be defective as they have a tendency to stick to the floor of my gunsafe, like its melting to the carpet in there. I've read of many others that have been having the same problem. I don't know if its just the Savage pads or all the Sims line. Might want to search around a bit for confirmation. They do dampen the recoil quite well aside from the melting problem.
