If you are having extraction problems then the 25% extra power Wolff spring may be your solution. The other is to adjust your extractor knob. See article in Tech Forum.

Extra power magazine springs help improve feeding. Highly recommended for anyone having magazine problems with 10mm and 38 super using factory followers. Cut one coil when used with plastic or short bsae pads (H-400, H-520). Use full length with H-141.

For a lighter trigger pull, switch to Wolff's reduced hammer spring.

Just made available a long transverse spring which is for the older Tanfoglio / EAA frames. These frames are 80's and maybe early 90's guns. But with this lighter hammer spring and the long firing pin you can re-vamp your old gun!

The absolute leader in recoil springs and my first choice when upgrading the guns. Available in 6lb (non-compensated guns, steel loads), 8lb (compensated guns, steel loads), 10lb (major, ipsc loads) and 12lb (major, ipsc loads).

Henning's Comment:

I've suggested two choices for steel loads and major loads. What works best varies on your individual gun caliber/setup and loads. I suggest trying different springs to see what functions best in your gun with your load and what feels best for you. I do not recommend less than 10lb springs for major loads!

New April 2009: Introducing Henning 10.75lb recoil spring. I shoot mostly Limited 40 S&W in USPSA and IPSC competitions with a 180 grain bullet factoring 170-175 power factor. This is the spring that perfectly tunes the Tanfoglio / EAA Limited 40 S&W for major power factor loads.
