Does anyone sell the Delrin strips precut for HW's? I took the 30s apart for the first time since it was new and noticed some galling. I've got about 5000 rounds through it so it's not bad (no where near as bad as the pictures make it look). My 50s has the strips and doesn't do it, no scratches on the spring guide either because the strips push the cocking shoe out just enough to miss it. Or should I not even worry about it and just shoot it? I lubed it up good with some moly and it cocks smooth as butter.
