Thank you to everyone that commented in the PDW opinion Thread! It all came together because
Building a custom PDW gives the end user the ability to mold the firearm into the requirements that are not only needed but essential to either getting off the X of an engagement or the greater ability to fall back to a plan B. In any case the options you need in this possible predicament can be articulated through a build of your choice knowing all the possible constraints that your daily environment or aggressor may throw at you. Sticking with these core requirements and not settling for less will generally give you an advantage over someone who has not taken this into consideration. Spoils go to the one who trains and prepares more and better that the opponent.
