+1 on DD. I love my DD upper w/ Rock River lower. The lightweight barrel w/ omega rail is worth the money. I built it myself after doing much research and the knowledge of the guys from ADCO firearms(http://www.adcofirearms.com/
). Fantastic service and knowledge.
You guys are making me want to get a 1911 as my next purchase. I had originally been looking at a revolver as my next purchase, specifically a S&W .44 mag or .500 mag.
My collection so far:
H&K USP 9mm
Mossberg 935 semi-auto 12 ga
1970's Remmington 870 Wingmaster(back when "wingmaster" meant something)
AR15 DD upper/RR lower
