Long time GT member, first time in this group. I watched a Seal Instructor on youtube talk about the Sig 226 being a backup weapon to the MP5. He said they use the triple tap two thru the heart and one to the head. I tried this on shiloute targets at the range and find it fairly dificult at 10 yds. Is this practical as the perp won't be standing still? What are your ideas on single vs double vs triple tap?
