Recently did a trade for a 390. The shells aren't ejecting all the way and the bolt is not coming all the way back. Gun has been cleaned throughly. The front spring is "green" in color. It is not ejecting Top Guns or Estate 3dram.

Question is: what color should it be?

How is gun lubricated? Mine will handle 7/8 target loads with Green spring.

I prefer CLP BreakFree. Here is my routine:

Several drops on the rod that the piston runs on.
Three drops between the piston operating bar and the receiver.
Three drops on the base of the operating handle (let it run down into the bolt)

I do this every time I shoot it. I can run 5000 to 8000 shells through it before I need to disassemble and clean.

The green spring should normally cycle 3 dram 1 1/8 ounce loads unless the gun isn't broken in or unless it isn't adequately lubricated. In fact, the green spring will often work well with 1 ounce loads and sometimes even the 7/8 ounce loads.

BTW, when was the last time the recoil spring was removed from the buttstock and cleaned and lubed? If you've never done it, then I suggest that you do that before buying additional gas springs which really may not be needed.

Lube everything up WET with Breakfree CLP and try again.

I plan to remove the recoil spring this weekend and clean it but I will still try some other colors.

Thanks for all the help.
