Shooter's Paks include a Wolff reduced power mainspring, a reduced power sear/bolt spring (traditional flat-type or wire-type), extra power base pin spiring and stainless steel hand ejector spring.  These kits offer great improvement in the trigger and maintains reliability.  See individual spring information below.

Wolff Single Action reduced power mainsprings are a unique design with the center material of the spring removed.  This greatly reduces trigger pull but maintains the balance of the spring resulting in a smooth, reliable action.  Used in combination with Wolff reduced power sear/bolt springs, a great improvement in trigger functions is achieved with only a spring change. As there are variations in these guns, exact measurements are not possible. EMF Hartford uses Colt Springs. Most clones not listed below should use Colt springs -fitting may be required.

Wolff sear/bolt springs for Single Action revolvers are available in the traditional flat-type or in wire-type.  Both are reduced power. The wire-type spring offers the greatest improvement in function for as smooth, light trigger.

 

 

Flat-Type Springs (Stock No. 32290-32292)  fits:  Colt SAA, EMF, Uberti, and most clones
Wire-Type Springs (Stock No. 32294-32296) fits:  Colt, Uberti, an most clones
Wire-Type Springs (Stock No. 32297-32299) fits:  EMF Only 

Base pin springs are used on Colt, Uberti and many clones. Not used on the EMF Hartford.  This critical spring latches the cylinder pin in place and is often weak or too light. Wolff extra power base pin springs provide positive latching to help prevent the possibility of the cylinder pin becoming unlocked.

Wolff stainless steel hand ejector spring replaces original spring which is commonly weakened from rust.
Fits Colts and most clones.
