on my experience.. Tungsten adds more weight. Use it together with heavier recoil spring = tameable recoil.. **low grain ammo will reduce recoil too..
A heavier spring will increase felt recoil. When competition shooters want less recoil they will put a lighter spring in and clip a few coils off. This is what needs to be done if you want to decrease felt recoil. http://www.custom-glock.com/springtech.html
Is there a guiderod/ spring combo that you would recommend ? Any certain brand? I have a 9mm but I wanna be more accurate with less recoil
Go here. Get the rod spring combo in the weight you want. And order a few extras in different weights. You will have to experiment to see what you like best. Get a 16#,15# and so on. Clip off one coil at a time until you get the feel you want http://www.gunsprings.com/index.cfm?page=items&cID=1&mID=5#123
