I have been thinking about changing the spring in my Norinco 45TT sport model. It has the factory spring at the moment but would like to update it a wee bit. Not sure what weight it currently is but can probably contact them to find out I suspect. For the price its actually a heck of a well made gun. We call them our Chinese Kimbers up here.

Great post DA; very informative. I bought a gauge so I could measure my recoil springs, but by viewing the video, it appears what one really needs is a high-speed camera to fine-tune the recoil springs.
I was not aware of the dipping down of the muzzle with a heavier recoil spring.
