Best of luck on test firing it. I bought a 442-1 NIB this summer, about 150 rds so far with factory ammo without a issue. I bought it because I needed a 100% never fail carry weapon, If I had your issues with it I would send it back to SW period...they built it...they know all about it...they can fix it. I would NEVER NEVER fool with opening up a New Pistol or Warranty covered Model that can void the Warranty if they detect you've fooled with it. Again good luck.
