Lemme add... The difference in a plinker and a defensive firearm is that a plinker can hang up or fail to fire and it is just a break from the plinking... a broken plinker can sit in the closet for infinity and only your plinking time suffers...
The SD/HD weapon doesn't have such luxuries... It must come to service and serve when called upon with out fail each and every time...
The amount of rounds some send down range to prove reliability is close to or exceeding the lifespan in round count of some of the "lesser" arms coming into the market today...
