I'll answer in two parts:
Nostalgia:
Remington 700 - Proven platform, lots of tuning options/parts available, police and military favorite
Colt 1911A1 - Feels just right, a piece of American history, lots of tuning options/parts available, beautiful weapon, combat proven, combat accurate
Browning A5 - auto feed, piece of American history, great handling shotgun
Performance:
Rifles Inc. Lightweight Strata (5 lbs.) - Customized to your design and super light for walking up on coyotes or taking long shots at ground feeding crows, sub MOA accurate
Glock 21* - proven reliability, simple design, decent trigger, lots of capacity, very accurate
Browning Gold - pleasure to shoot, excellent patterning, auto feed from bottom
* Glock 19 for concealed carry
