It jams with Colt mags too?

We have a local cop whose 1911 jammed consistently. He used Chip McCormick mags exclusively. When the mags were swapped out for 7 rd Colts and GI mags, it fed and fired flawlessly.

Since the gun jammed with several magazines, it might not be the magazine. That slide caught the extractor groove in the round it is trying to feed. That usually indicates that the slide did not recoil far enough to catch the rim and caught the groove instead as the round tried to rise.

That would point to a possible ammo problem or a too strong recoil spring. You say the gun is "super tight" and that could also slow down the slide and cause it to stop too soon. If that is the case, the gun might "break in" but I have no way to say how long that would take unless you work it manually or use an abrasive to loosen it up.

Polish the feed ramp?....

I'm not quite sure if it would help but it couldn't hurt, .
A pistolsmith can polish the feed ramp. That can help with feeding/cycles.

Hi guys thanks for all your replies. I polished the feed ramp and the rails took it back to the range it ran 100 %.
