Most weapons are changed to reflect their real-world selves. I included the hunting rifle's madly high-powered mod that nobody seems to like using however handy it is, and a more moderate version of that as the AWP. Assault rifle magazines are down to 30 rounds. Sniper rifle magazine is down to 10, but the reload is faster now. MAC10 (silenced SMG) is horribly inaccurate, has a 30-round magazine and empties it at 1145 rpm, per reality. Uzi is more accurate, but not quite as good as in my Uzi buff. Pistols are markedly less accurate. Shotguns have the biggest change: they're more powerful and have much less spread.
