Also the Magnetospeed has a hard time staying put between shots on the pencil barrels. On my fatter barrel it does ok, but after a couple shots on my Kimbers I am stopping to redajust and retighten. It works and I certainly like it better than my beta chrony but there is enough about it that I don't like that my big Christmas present request is a Labradar.
Smearing the strap with Shoe Goo or silicone will cure the migrating problem.
