    Colt Mk IV Series 80 feeding issues

    So about a week ago I got sick of trying to carry my Glock 30 concealed and wanted to try out a 1911.

    Purchased a Colt Mk 4 series 80 from a local gun store for around $700 used.

    Upon inserting a loaded magazine and racking the slide to the rear I noticed the round misfed. I ejected the round to find the bullet had been depressed inside the casing. I deemed the round no longer safe for use, discarded it, and put a new round in the magazine. I racked the slide to the rear again, only to have it misfeed yet again.
    "It must be a poorly fitting magazine" I thought and went to the gun store to purchase another magazine. Same problem with the new magazine.

    Upon disassembling the weapon I discovered that both magazines had a lot of wiggle room when in the magazine well, and moved up and down somewhat more than any other weapon I own (I own a few Glocks, an old Smith and Wesson wannabe Glock, and a mil-spec Beretta M9). I can't find anything on the internet addressing this problem. Could it be some other cause, or am I correct in assuming its a problem somewhere within the magazine well?

    Thoughts and advice from more experienced 1911 owners would be greatly appreciated.

    What type of mag did you purchase? Just because it's new doesn't mean it's any good, or the follower design is correct.

    Buy a Wilson 47D mag and try it before you cast judgement.

    Being a used gun, it's also possible the previous owner did some " stupid " improvements to the gun.

    If the gun is stock, and the Wilson mag doesn't fix the problem, then the next logical culprit is the extractor.

    With the barrel in the frame & your slide stop pin inserted in the barrel link push your barrel all the way back & down and make sure that your barrel does not overhang the frame feed ramp.

    Oh boy, being used and you not being familiar with the platform, I'd say Gman and QKS maybe onto something, your Colt very well could have been bubbafied. Magazines in a 1911 are not normally tight fitting, but by the sound of your misfeeds, I think QK is closer with his thought the feed ramp has been messed with. Many folks that think they know the 1911 "polish" the feed ramp until there isn't any ledge between the barrel throat and feed ramp, JMB designed it to have a small shelf there, it actually helps feeding, if removed, it hinders feeding. It should look like this when assemble as QK suggested;

    I don't think it is the Gun or the magazine. What kind of ammo are you using?

    Dang! I feel completely proud to even be mentioned in the same post as QK as being potentially in the ballpark with respect to the 1911 by OD*.

    These guys are my go to heroes when it comes to the 1911.
    I am learning guys! One of these days I might get there.:)

    Jm,

    Does it seem like a loaded mag "sinks" out of the magwell after you insert and seat the mag?

    Try applying upward pressure on the floor plate / base pad of the magazine when chambering a round. The mag catch may be worn or out of spec allowing the mag to "ride low".

    That is another possibility, easily fixed with George's oversized magazine catches.

    Meg-gar is the company that manufactured the new magazine.

    It doesn't appear that anyone has messed with the feed ramp. I should mention the first round appears to be nose diving, and whenever I remove the magazin after the misfeed the second round is pushed forward in the magazine. A friend of mine tells me this is not normal.

    Mec-Gar makes a quality magazine, BUT the pair I bought for my 1911s were iffy. Out of those, plus Shooting Star, King's, OEM Springfield and Kimber, Cobra (Tripp) and "genuine" GI mags, Wilsons (47D and ETM) are the only mags that have never let me down.
