Sistema Disconnector update and some advice needed

[Audie]

I have determined 100% that my binding disconnector is a result of protrusion into the mag well. I placed a block of wood against the hole inside the magwell and could not push down the disconnector with my thumb. then putting my little finger over the hole I can feel the disconnectors edge push on my finger as I push the disconnector down.

with loose fitting mags this is not a problem, gun function tests fine and shoots fine. With tight colt mags this is a problem.

how should I fix this? Should I detail strip and sand down the sharp edge on the disconnector that is protruding, or just find mags that don't cause the problem.

Also, how does this occur? I find it hard to believe this was the way the gun was off the line in 1953...is something put together wrong, or could it be that something else is pushing it out of place?

Again the gun function perfectly with the loose mag that came with the pistol.

thanks again for the help.

It's probably not the original disconnector in the pistol.

Work down the area that is protruding into the mag well.
It's an easy fix.
I'll post a link to the fix if I find it.

the pistol showed no wear at all before I shot it...so I am thinking it is original to the rearsenalling...but who knows what happened in argentina before it was shipped here.

If you could post the link, that would be great.
thanks.

This is a link to brownells bench talk on how to set a 2 1/2lb trigger. What is important to you is Figure 1 on page 2 shows a disconnector before and after.

You only have to touch the forward lower corner a little bit.

Because the pistol was refinished, they probably batch finished the small parts. So the pistols probably did not get the original parts put back on. Or they could have just replaced the disconnector because the original was worn.



PLEASE DON'T TRY SETTING YOUR TRIGGER TO THESE INSTRUCTIONS LEAVE THAT WORK TO EXPERIENCED GUN SMITHS

thats probably what happened, they swapped the part and never function tested it with a tight mag...typical....I checked the link, looks easy enough...thanks.
