Ok a little mod, since pistols are always slot 2.

pawn Код:

new weap[2];
   GetPlayerWeaponData(playerid,2,weap[0],weap[1]); // weap[0] is the weapon, and weap[1] is ammo.
   if(weap[0] == 22 || weap[0] == 23 || weap[0] == 24)
   {
             GivePlayerMoney(playerid, -200);
             SetPlayerAmmo(playerid, GetPlayerWeapon(playerid), weap[1]+20);
   }
   else
   {
         SendClientMessage(playerid, COLOR_LRED, "You don't have the right weapon for this kind of ammo.");
   }
