Hold Open Assembly

In addition to the solid advice already offered I would add:
1. Make sure the hold open spring is fully pushed in so that it doesn't scrape on the frame and interfere with operation.
2. I have one hold open in a '38 Mauser 'shooter' that simply sits low, even though it is numbered to the gun. The pressure required to manually lift this hold open is not excessive so I don't think the hold open spring is the issue. Magazine expert G.T. saved the part by trying many magazines until we found an older Mec Gar with a larger follower button that would push it up enough to work.

After about a year of perfect operation, the hold open returned to its unreliable ways even with our "special" magazine. G.T. then installed a stronger magazine spring, now at 18 months and counting this 'rig' is holding-open perfectly on last round. So my experience is, when nothing else works, consider different mags/stronger magazine springs.
