A lot of jackets have draw cord adjuster at the 3 o'clock and 9 o'clock positions, which happens to be the area where we carry our guns. So it was a matter of time before an accidental discharge was caused by the adjuster getting stuck in the holster or trigger guard.
Here is
one with graphic photo of wound from Gun Digest
Please be careful when you wear clothings with these adjusters. No need to holster fast since no shooting is won by fast holstering. Some people get rid of the adjuster, some people use duct tape over it.
