I'm a tad confused by Secret Agent Man's seeming detailed concerns about check out lines & horizontal shoulder holsters.
Is this a serious issue to cause concern?
FWIW: I toted a large NP3 plated Beretta 96D .40 in a left Aker comfort-flex shoulder holster. I once drew the 96D so fast, my friend was surprised by the speed.
My main point is that training & safety are what's important when dealing with firearms or gear.
A lot of "hard chargers" or "weekend Rambos" may want to wag their fingers or ball out other gun owners/shooters but I take a different approach.
I TALK & LISTEN to other shooters-gunners FIRST then offer my input.
As posted already, I too give the "Tex" guy credit for being honest & open.
