-Noticeably less recoil
-Greater efficency (i went from 700 shots out of my 68/3k; to *1300* shots!)
-Makes your 98 HEAVY, HEAVY, HEAVY
-Must purchase a regulator to install
-No beavertail available for it yet
These retail for about $120. Although i have GREATLY enjoyed the benefits of this kit; when weighing it's pro's & con's, it's really just too much for what you get. If the price were lower, i would say go for it. But you're going to buy the kit ($120) then a regulator ($50-100), and when you're done, you'll have spent almost enough to buy an electronic gun. (Impulse, etc.) I'm giving it a 7 because of it's HIGH cost. If it were cheaper, that would change things.
