As a younger man I immediately got out to shoot my newest acquisitions. How times change. Christmas before last I received a Lone Wolf 9mm barrel and a Ghost Trigger 3.5 Ultimate COMPLETE Trigger Kit for my model 22. Got around to having an experienced smith do the trigger work about eight months ago. Got to the range just last weekend. I'm very pleased with the trigger and the accuracy of the LW barrel. I get better groups with it than with the stock 40S&W barrel. Trigger pull is right at 4lbs (per smithy). Left the original firing pin in. Take up and over-travel feel better although I don't have a stock model to compare it to. It loves the SIG 124gr ammo, but not the cheap 115gr stuff. Ejection problems every 15 to twenty round with the 115gr. The 124gr ammo cycled with out incident in the 80 or so round fired and printed better than the 115gr ammo. Just wanted to share.
