Even last shot didn't bring toggle up.

So far I read that I need to start with mag, is this correct you think?

What ammo is best to try ?
some guys advice more powerful ammo, is it 125?
All above is not FMJ, and I don't want to use it.

Please share your experience, I don't plan to fire it every day, just want to sleep good knowing that I have good condition gun.

Anybody know any good luger pro in SF Bay Area (USA).


Thanks
Mario

Mario,
take it a step at a time.
You must, IMO, start with "known" ammo.
Winchester White box std. velocity in 115 fmj or 124 g fmj is ok, do not use Winchester or any other "Nato" 124 g loading.
S&B 115g ball also works for me. As does 115 g PPU. But go with the WWB if you can find it.

First, strip, clean, and lube with good OIL.

Load one round in the magazine, charge and fire.

If the round ejects and the toggle locks open, move on to a full mag.

If the round does not eject- check:
-ejector
-extractor hook, spring, clean seat

Try one round again.

If it does not trouble shoot at that point, could be:
-hold open broken
-magazine problem, buy a new mec-gar or borrow known good mags and try them
-Mainspring may be too strong- but I doubt it, would be dang near impossible to get in the action

Try the full mag to determine loading and ejection reliability.

Report back in!
