So realistically, there are only two things that are different between the first shot of a full magazine and the subsequent second, third, forth etc. shots.

1; The temperature of the barrel / chamber.

as the chamber warms up, it should expand ever so slightly, thus giving slightly more clearance to the chambered round.

2; The upward pressure exerted by the loaded rounds pushing up on the bottom face of the bolt.

This pressure reduces as rounds are stripped out of the mag.


Every other function of the gun's mechanism is identical from the first to the second last shot of a mag.


You said that you replaced the ejector ?
Can you upload some photos ?

You mentioned that the fired cases are now being ejected/jammed differently.
This could be a clue, as I cannot see any reason that they would end up facing the opposite way. Impossible in fact, unless the ejecting round is somehow spinning 180 degrees whilst still inside the frame.
This point is very strange indeed!!

More likely that the spent round is being "ejected" (hitting) by something OTHER than the actual ejector, and/or the extractor is not holding the spent case firmly against the bolt face.


Does the slide still lock open after the last round is fired ?

Have you fitted a recoil buffer ? is the slide moving thru its entire stroke range?

Pulling the slide back, how far past the slide stop does the bolt face travel ?

The slide release lever needs to locate under the safety lever detent plate. Can you confirm this ?

Have you tried your slide on someone else's frame ?

Have you tried someone else's slide on your frame ?


I would put the gun down, grab a coffee, take a few very deep breaths and start your diagnosis again.

Absolutely confirm each and every item that has been suggested to be checked.
Double check and triple check before moving onto the next item.

do the "plop" test ( round into barrel chamber unaided )
do the "wobble" test (round being held against the bolt face with sufficient force )

It almost looks like you are getting lost in a whirl of trying a thousand things all at the same time.

Step back, re-focus and start again...... slowly

You did mention that after lubing 100 rounds, the pistol performed faultlessly ??

To me, this is simply indicating a tight chamber.
You did say that however, you checked the chamber and said that the rounds would drop in and out under gravity?

BUT, you also said that you tried a friends barrel, and the issue remained ?

So confusing.....

It still could just be a weak batch of ammo.

Have you tried some CCI SV's from a different production batch ?

If you have access to a chrono, maybe have a look and see what muzzle velocity you have with the ammo that you are using ?

Remember, these are very simple machines.
They only need a number of actions to happen in the right way and at the right time for it to operate correctly.

Don't give up !!

but,

If you cannot resolve this issue yourself, maybe you should just find a reputable Gun Smith who has extensive experience with the model 41 and have them check it out ( providing as much detail relating to your attempts to resolve the issue as possible )

Good luck !!!
