Daniel, First..congratulations on joining the Forum and your new Artillery.

The mismatched bolt is not a good sign or all that good for collector value. Any mismatched part is looked on as a detriment to a true collector Artillery.
However, as you intend to shoot this pistol, it will not be the only mismatched part soon enough. My shooter Artillery has had parts fly off on regular occasions.
Regardless..your pistol seems to be ammunition sensitive. If it was working faultlessly on MagTech..I would try again and see if it continues to do so. This simple test would tell you if the pistol changed in the middle of your shooting session or if it was the ammunition change.
Many members here have good luck with Walmart white box Winchester bulk ammo. It works well for me.
Another thing might be to find a MecGar mag to shoot with. The spring in your original wood bottom mag may be weak. Besides, if it matches the pistol you sure as heck don't want to break the wood bottom. Even if it does not match, you don't want to un necessarily risk breaking an original mag.
Untill you test your ammo, I wouldn't start monkeying with the mechanics of the pistol..Yet.

In the meantime, I would dismantle the pistol and look very closely at the hold open, sear, underside of the bolt, fireing pin and spring, trigger & spring..basically all the fireing parts. Look for wear,fractures, cracks, spalling..anything that might hamper operations. I bought a pistol once where a previous owner had replaced the trigger spring with a ball point pen spring. Worked for awhile!

You can also test fire the pistol once or twice without ammunition..a snap cap is always handy, to see if it functions normally at the bench.
From your description, it might be some grit or carbon build up.

If you repeatedly pulled the trigger and the pistol eventually functioned, the striker let loose and it tells you the pistol was cocking. Just that the sear was not releasing the fireing pin.

You may want to slip out the sear bar and clean underneath it. Might be a build up of crud there. Most people who clean Lugers fail to remove this important part and give it the attention it deserves.

It is simple to do, There is a flat spring that holds it in. Take a wood or plastic stick and insert it into the curved end of the flat spring. Lift it slightly and push towards the sear bar. It will slide over the bar and out of it's recess. Then the bar is free to come unhinged from it's post in the frame and can be removed.


Good Luck!
