Without expanding on an answer here... I will only refer you to all the many posts I have stuck on FRN directly related to this subject and the short answer is...
Low impact is the only way I go... very low... in fact, if you see me on a case... you only see an old fart dressed to go to Disneyworld or fishing... and it has always served my purpose rather well... I will not say I am not armed or prepared but you will not see me as a Swat member coming at you... if I need more than this... I just call one of the big guns on here, they do all my heavy hitting... and most of them are low key also.
I am an old man with two titanium knees and 3 back operations... and I am scared to death of someone hurting me so I try to do it easy...
I have a dozen of those big red "EASY" buttons you get at Staples all over my office... and I hit them daily...
Also, I am the president of the TSC.... run a search for that!!
and I haven't had to shoot my weapon in almost 3 months... (although I do practice usually weekly) I am deadly on doors and leather recliners... and an occasional electric heater...
