Jobiin,
I had feeding issues with an old MAB model D in .32ACP, I had ordered a new Triple K mag for it hoping to correct the problem. Nope, I then ordered an original used mag, that fixed it. But this doesn't end the idea of the story, I examined the Triple K and the O.E. mag. The difference (and problem) was the cut out on the front of the mag where the bullet is striped out. The Triple K has a shallow cut out while the O.E. had a deeper cut out on it. This was catching the round getting stripped off, kicking the bullet up instead of forward. Any way, I just wanted to mention the cutout on the front of the mag, that might be a possible issue.
There is a post here on TFF, just look for MAB model D feed problem. There are pics showing the problem I had.
