Well I have decided to use my recently aquired 67-1 4in s.b. for carry. Ray (LOBO) made me one of his new style IWB holsters with the clip to the rear of the cylinder reducing the bulkk, works great. But I soon discovered the Pacs were just too big for carry. So I went to the original PC service grips, these conceal a little better. But I really need something to fill a little of the space behind the trigger guard. So I'm looking for some help with grips, maybe some boot grips? Seems all the boot grips I see are for round b. Does anyone make a good carry boot grip for the square b?
