Neat comcept, I guess, but it seems like a solution looking for a problem.
I carry every church service, usually under a suit coat. Every Sunday and some Wednesdays.
Some of these times I am even preaching, like last night. TypicallI carry my full size 1911.
I have been doing so for about 10 years.
I am also head of our security.
In all of this time, I have never thought, man, I could really use a tactical suit coat.
Maybe this is fine for the large/mega churches who's security teams are more like small law enforcement agencies, but this seems overkill for most folks.
Also, MSRP is $170 to $200 (not surprising for 5.11). I have paid less than that for every suit I own.
If it was $100, I MIGHT consider one. But not pushing $200.
I love my 5.11 tac pants that I wear on duty (just wore a pair last night) but their approximate $70 price tag is crazy.
