I went shooting today and I noticed the toggle mechanism on my 1900 AE - 30 cal. was acting funny. The toggle was not completely coming all the way down after each firing of the gun. It would shoot fine, extract the spent shell fine. But after that every so often the toggle would not come completey down. I would have to push it down with my hand. I thought at first not enough lubrication, so I stripped it at the gun range and added plenty of lub (Hoppes gun grease). Thick grease almost like lithium grease along the rails for the sliding portion of the toggle and frame.
All being said that helped a little, but every so often I would still have to push the toogle back down all the way to fire again.
After getting home I did some looking at the gun and spent shells. I noticed the spent shells on the back side where the firing pin hits the shell, had different depths of indentions on the primer.
As looking at the upper frame where it rides in the groove on the main body, I noticed some unusual wear on the frame.
So Anyone got any comments on this issue with the toggle. I also did some further inspection on the entire gun. See next thread.
