I hear a lot of questions about installing a tungsten guide rod in their guns. Well I bought a G22 that has one installed and the standard rod was also included. So I will be putting it to the test . I am going to take it to the range and fire with both rods and see if , in my opinion , there is a difference that justifies the $50 upgrade. I will try 2 or 3 different types of ammo and I will post the results in this thread,I hope to do this by Wednesday .
