Q: Is there an issue with the early S&W 686 revolvers fitting the DAA Magnetic Insert - L/K Frame?
A: It has been pointed out to us that the early S&W 686 Revolvers have a slightly thicker trigger guard which effects the ability of the DAA L/K Frame Magnetic Inserts to fully engage.
The solution is to widen (evenly on both sides) the slot the trigger guard sits in, until it fits. Remove the minimum amount of material possible and do this very gradually. Remember: Less is Best.
