Nice gun.My 97 has become one of my personal favorites. I've got approximately 5,300 rounds through this one and it's very smooth. It's outfitted with a CZ Custom Shop Competition (CS) hammer, CS sights, Hogue grips, and a custom machined/fitted 1911 barrel bushing. Firing pin spring, extractor spring, and hammer spring are the originals (recoil spring is a Wolf). Nothing has ever malfunctioned or broken; I've run it 1,000 rounds w/o cleaning. Nothing I own can outshoot it for accuracy
