To be absolutely honest about it, I've never been a fan of the AR-15. This goes back to some bad experiences with Uncle Sam's M-16A1 back in the early to mid 1970s. Swore I'd never own one.
But a couple of years ago the antis were in full Ban 'Em mode, I finally gave in and bought a M&P Sport II just to have one and piss 'em off.
Nothing real fancy. I've got it set up for close to intermediate range use.
Well, since I had already made the plunge, I got to thinking about a PDW. Preferably in a pistol caliber because I've learned that AR pistols in rifle calibers are darned LOUD!
I settled on the ARish Extar EP-9 in 9mm. Maybe not the most practical weapon, but I can take it over to my clubs Action Pistol range and its an absolute hoot to shoot!
