Zoomer Sr. here. Real guns....hmmmmm I love em. Not into old military stuff per se, but have shot many. Only military styles I own are a 1911 45acp (a sweet Kimber) and a new RRA ar-15 in 223/5.56. It's set up more like a varmint gun (scoped with a bull barrel, bipod etc.) and is EXTREMELY accurate. Other gun are primarily for hunting (Deer slug guns, O/U 12 Ga. Skeet/bird guns, 30-06 ruger M-77 for deer..50 cal Omega muzzleloader, etc., etc. I also have a Smith & Wesson 629 in stainless - a 44mag for the really ornery critters. My friends all shoot too so we have the opportunity to shoot lots of other stuff - even Desert Eagles!!
And here's another thing that bothers me on CS - Why is the M4 a left handed version? Shells should eject to the right for a right handed shooter w/the ejection port on the right side and every time I switch back to it (say from using a pistol) I pull the charging handle - that is not how the gun works. Charge it once, slam the bolt home and she's locked and loaded, and ready to rock and roll.
