There may be a lot of reasons why two shots to an attacker's vital zone fails to put him down.
Mossberg expanded its new handgun lineup in 2020 with the release of the MC2c, which offers a step up in size and capacity over its initial offering.
The justification for the exercise is the fact that we have applied two hits to the vital zone of the attacker and he is clearly unimpressed with the results.
My colleague and friend Jim Wilson recently commented on the Failure Drill. In doing so, he kicked over a hornet's nest.
The Failure Drill consists of three shots designed to ensure that an attacker is stopped by putting two shots into center of mass with a final shot to the head.
