Default Model 41 fails to fire on last round in magazine

Question for the more knowledgeable Model 41 people. I have a Model 41 that functions flawlessly for 9 rounds, then always the last round in 5 different magazines, will fail to fire on the 10th round. As best I can tell, the hammer is following (not staying cocked) on the last round in the magazine. An extremely thorough cleaning made no change. That's the only problem with it. All other functions work fine. Mags insert easily/drop free easily. Safety works properly with positive, although stiff, detents. I normally never use the safety anyway but for testing purposes tried cycling it a few times. Tried 5 different 10 round steel follower magazines and 5 different 12 round orange follower magazines. I'm at a loss... Any and all suggestions welcomed.
Thanks

Because you state this happens with all your magazines and not just some I would say you could possibly have a problem with the magazine disconnect mechanism and the problem occurs when the magazine spring is at low tension. Without the gun in front of me I am just taking a swat on what it might be.

Normally most problems stem from the Magazine itself, but you said you did try many steel follower and plastic follower magazines and the odds of having problems with all of them is extremely miniscule.

BTW, check to see if all springs are where they are suppose to be!!

Check the underside of the slide where it bears against the cartridges and make sure there are no irregularities.

My thinking is the last round sits at a different angle than the subsequent rounds and that might be slowing the slide down to the point that it is not travelling all the way back and not cocking the hammer.
