Using the GP strap sling over the strong shoulder, the hammerhead works pretty well gripping it at my waist, suspended from the sling. When I throw it up to the shoulder to fire, however, that is where the hammerhead looses its appeal. With the paddle, the trigger finger or thumb of strong hand can manipulate the ambi safety without shifting the strong hand grip. The hammerhead is easier to use the off hand to manipulate the regular safety lever on the left side.
Morg, as for move to "free America", I own a house that is being used as a rental (think God for the income from that) in the Coos Bay, OR area. However, "She who must be obeyed" will NEVER leave California and the grandkids, especially out 2 1/2 year old grandson who lives 5 minutes from us, and spends at least half his time with us. Therefore, it is making the best of a bad situation! It could be worse. I could be in NJ or NY!
