Aero is my go to for receivers. Their not overly expensive (on big daddy unlimited right now you can get a matched upper and lower for 95 bucks) and they are very well made IMO. If there are weight savings with a billet lower it isn't much, and since you are concerned with recoil (mostly with the pistol but still) having a slightly heavier gun could help with that. I'm not a trigger snob either, mil-spec trigger is all you need in my opinion, bravo company's PNT is a decent one. Save the money where you can and put that into the barrel/optics/ammo. Pretty much all the barrels you mentioned are good, the brownells one is cheap (I have a 24" one that does .5" groups with hornady black), and look at the group buys on here to get a good deal on some really good ones.
