After 8 months Remington sent my pistol back with an extra magazine. They had to cut the slide off because breech block was hung up in it. Wished I had asked for the old parts to be sent back. I'm still not happy about how the breech block is working on the aluminum frame but we will see how it goes. Works well, occasional second round hangs up in magazine forward indent.
What type of ammo are you using? Are you shooting 7+1? What is your gun's serial number (for build date)? Just curious if you are still having failure to feed/failure to fire.
