Hey Zigg!
In my opinion you should try these three out:
1. Infiltration - "Real" weapons on UT maps and player-made urban maps. Downpoints: You can carry all weapons at the same time... Not a lot of online players... (New version on it's way. Out real soon...)
2. Strike Force - Strike Force and Terrorists battle it out, "real" weapons, and different characters with different fav weapons, can't carry more than two weapons. Downside: Still buggy... Bots don't do squat... (New version on it's way. Out real soon...)
3. Tactical Ops - Hostage rescue with SWAT vs Terrorists, "real" weapons, you have to "buy" new weapons and ammo for money you make during the missions, can't carry all weapons around. Downside: Limited playing styles (yet)... Sounds like you're wearing high heels when you walk around... (New version on it's way. Out real soon...)
They all have pros and cons, so just download 'em all and try 'em out. Well, that's it from me.
Happy fragging, and welcome to our community!
