Older M&P Shield Performance Center vs. newer Std. M&P Shield 2.0

Looking for a CCW. Cannot decide if I should get the older Shield model with the Performance Center setup or a standard M&P Shield 2.0 and throw new sights on it. There are good deals on the older PC models right now, but I like the grip, trigger and stiffer frame (supposedly more accurate) of the 2.0. I’d have to add new sights to the 2.0, so it’s a chunk more $$. Money is not a HUGE issue, but it’s a consideration. I know S&W will eventually make a 2.0 in Performance Center config. but who knows how long that will take.Thoughts on either of these weapons? Which would you choose? via /r/CCW http://ift.tt/2DU688Y
