Update on my Amazon mount:
Works fine with the exception of sliding during recoil. They included some peel and stick rubber pads with it, but they appear a bit thick. I’m going to cut a couple strips of no-skid tape to put between the mount and barrel/mag tube. That should secure it nicely. Found out tonight how damn inadequate that original P61 bulb is. Coyotes out back were danger close this evening and I didn’t have enough light to take care of business. I was “reverse-Acme’d” Meep Meep!!
