A lot of high end meters don't have specific low resistance ranges, but they have enough accuracy and resolution to measure far lower. For example, the classic HP 34401A's 100Ohm range is accurate to 0.004Ohms.
As you noticed, DMMs don't really specialize in low resistance measurements. Part of the problem is that they simply don't source enough current. Usually only 1mA, which means the DMM can only measure 1uV / mOhm. So, as suggested, the easy thing to do is source the current yourself and then measure the voltage across the resistor using your meter. If you have two meters, you don't even need a decent current source, just measure the current and voltage simultaneously.
