I too just purchased a new BG38 from a local pawn shop unfortunately, I had to take the allen and tighten the laser a little to get it to make contact so the laser would come on. Long story short, I can't get the laser to tighten up and the bolt is stripped and now I'm waiting on a label and shipping instructions from Smith. I hope CT comes out with a grip for this soon. Minus the cost that would be the ideal fix to this particularly common problem.
