Nice upgrade
I replaced the plastic mainspring housing STI DVC Limited with this SS offering from Dawson. It fit perfectly in the Xtreme grip and did not need fitting to interface properly with the grip safety. I had to enlarge the grip pin hole slightly to allow the pin through, but that only took a couple minutes with a hand drill. Overall, the gun balances a bit better and seems to have less muzzle flip. I am very satisfied with the purchase.
