I had an unusual occurrence. I recently bought a Ruger New Vaquero, in 357 mag. The day I got it, it was snowing so bad I couldn't shoot it right away. I took it down and cleaned it so it was ready when the weather was. I dry fired it only a few times. When I did go to shoot my NV, the hammer stopped at half way! I got it to shoot 5 times out of 36 times with the same factory, Federal 158 gr, JHP. WTH! I called Ruger, they said it was a burr, and to disassemble and check for burrs. Ruger would send a new hammer. After thinking, I said it wasn't my job to fix your problem with my gun. They then gave me an RMA and shipping instructions! WTH! Anyone ever had trouble like this? I'm going to trade it for a Blackhawk. Any Takers? BHK!
