I keep my knife in my left front pocket for two reasons.C-dub wrote:I had something similar a few years ago happen due to having my holster and knife on the same side. I switched the knife to the left front pocket.
First, if my right hand is holding a knife it can't be holding my gun.
Second, for retention purposes. I've practiced the scenario where someone is trying to do a gun grab from my holster, where I am trying to retain the gun with my right hand, while I pull the knife with my left hand and start slashing the arm of my opponent.
As for the OP, this is one good reason to shoot IDPA competing with one's actual carry rig. Equipment and wardrobe issues are better to work out on the range in competition instead of on the street when one's life is at stake.
