magazine problems

In a 70 Series, Colt Government Model pistol single stack Colt and GI magazines feed without problem. In a Kimber Custom Classic Target pistol, also a 1911 design, correct me if I'm wrong, the above mentioned magazines feed without problems. Chip McCormick Corp., Shooting Star 8 round magazines feed well in this pistol also, however in the above mentioned Colt Pistol, they simply are not reliable, resulting in cartridges jammed into the top of the feed ramp quite frequently. Same ammunition is used in both pistols.

Anyone have a similar experience, and or any ideas. Thanks.

Some magazine feed lips are longer or shorter then other, so you may have to adjust your OAL. to get them to feed reliable.

long feed lips release the bullet late.
short feed lips release the bullet to soon.

That is a possibility, however one set of mags works find in BOTH PISTOLS, the other in only one.

I did notice one thing perhaps of interest. Measuring from the bottom of the floor plate to the top of the magazine catch slot in magazines, the dimensions on Colt magazines were within a couple of thousands of each other. There was a greater variation in the Shooting Star Magazines, and the dimension mentioned above was SHORTER in the Colt Magazines, than in the Shooting
Star mags. Once again, the Colt and GI magazines fed in both pistols, the Shooting Star mags worked in only one pistol, the Kimber. How does that strike you?
 
I think if the mag catch slot was the problem you need to measure from the catch slot to the top of the mag, because from slot down should not make a diff.

Note: some feed ramp set closer to the magazine and the angle very alittle also.
 
It could be "magazine float". Your mag catch on your gun maybe out of spec just enough to cause the mag to sit lower in the frame, causing your problems. Or the mag catch on the magazine may be out of spec just enough, causing the same situation as above. Finding reliable magazines for a 1911 is a pain. Stick to Metalform, Wislons, and GI mags (mostly metalform anyway). Hope this helps.
