ok.
before anything else, what version are you ruinning? the installer should say v0.13b, that is current public verison.
Now did you read the readme? It has a lot of debuging stuff that I have commonly been asked. here is a link to the current (v0.14b) readme:

If that did not fix it, the dual pistols are in Karkand Knives, not strike at karkand. You go over the table (3 on the map total, one in each main base, the other I will let you find) hit use (default e) and then fire it. The table (hereforth know as the kit spawner) looks like (note not in that map, that just the only screen I have of it). It is vehilce like the tow launchers. When you fire it will spawn a kit on the table.
Also how big is the installed mod? browse to the battlfield 2/mods and select the fuzz folder and see how big it is (should be about 823MB) the installer (fuzz.exe) should be a little over 144MB.
