View Full Version : Which rebound spring?

February 19, 2005, 11:14 PM
Hello all,

I am new to this forum and new to revolvers. I have just purchased a new S&W Model 66 and am loving it. I bought a spring kit from Wolff to lighten up the double action trigger pull. I have learned enough from this forum to change the mainspring and rebound spring, but the kit came with three rebound springs, 13, 14 and 15 lb. I went ahead and installed the 14 for a starting point, but I dont know what to look for to tell if it is the right one. I'm assuming that the point is to go as light as possible before something bad happens, but I have no idea what that something bad is.

BTW, this is a range/target gun not a carry gun.

Too light of a rebound spring will cause slow or sticky trigger reset in DA and SA modes.

If this is a gun that might be used for defense put the stock springs back in it, they provide enough force for consistent ignition and a little insurance. Lighter weight springs can and in many cases do reduce reliability.

For a range gun only the reduced springs can be suitable.

You can't go wrong with any of them if it's not a duty gun. They need more than springs to be tuned up. Good Luck.

When you find the ammo you're going to use, test it with different springs. Reliability first. Comfort second.
