Problem with bolt hold open on 1918 DMW

[Comanche1952]

I have a 1918 DMW which is in excellent condition, except that someone reblued it. They did a fine blue job, but there goes any collector's value. When I bought it, I replaced all the springs, except mainspring - just could not get the Wolff spring into the pistol.

Of late, I have had trouble with the bolt not locking to the rear on an empty magazine. The bolt hold open goes up and down just fine with the pistol field stripped and an empty magazine in the pistol. The hold open clearly functions.

But when I put the pistol back together, it won't work. New hold open spring and a little light dressing of the hold open arm didn't help. The hold open recess in the frame is clean and looks to be OK. I did notice that the cut out on the bottom of the bolt that presumably catches the hold open is a little nicked. But it was that way when I got the pistol, so I don't know if that is the problem.

Any ideas?

Thanks,

Jim
