    Cyecking out a new mag at the range today. It looks perfect and i xNt find any deformations in feed lips or anything. But i get an occasional bolt-over-base stoppage and the last round does this almost every time:

    And the original mag never does this ever. I'm thinking the new mag needs a fresh spring.

    Do officer mags take the same springs as gvmt mags?

    How the hell do i change it when the base plate is welded?

    Someone can expand on this but it may get you started...
    1. Push the follower 1/2 way in.
    2. Stick a toothpick, nail or ? in through a hole in the mag body all the way out the other side. You want to have it hold the spring from expanding.
    3. Remove the follower.
    4. Remove the spring (note the end orientation) by removing the pin.
    5. Go to doctor to remove spring from head.

    Symptomatic of a weak mag spring. The worse it gets the malfs will start happening sooner in the stack.

    What make is the new mag. What is the feed lip design on the new mag vs the old mag? I find it hard to believe that the new mags spring is weak unless it was purchased used. It is certainly possible but highly unlikely.

    I had a 1911 mag with the spring in wrong, turned 180 about the long axis, and it caused all sorts of problems until I took it apart.

    "New" mag is an exact match for the original. Colt pony, stainless, welded base 6 round, dimpled follower. Def. Not a fake. The spring length matched some new ones I had in the box but it has 11 coils instead of 8. Hope that fixes it.

    Thanks for the assist with removal. I would have launched that spring into the drywall.

    Bolt Over Base misfeed is most often caused by weak mag spring, but overspringing the slide can also do it. SO, if you've installed a heavy "recoil" spring to save the frame, go back to the old one.

    The 6-round OM mag takes the same spring and follower as the standard 7-round magazine. The 7-round OM magazine takes the same spring and follower as the flush-fit 8-round standard length magazine.

    Make sure the springs and followers are correctly mated. An 8-round follower with a 7-round spring don't play well together...and vice versa especially so.

    For the record, I put 7-round flush-fit OM magazines into the same category as 8-round flush fit standard length magazines. I won't allow'em in the yard.

    Thanks John. I put a Wolff +5% mag spring in it. The package just said 1911.

    I did not change the RTB spring but it's possible the last owner might have.

    I went down this road once before with a Kimber and never found a happy place. I'm taking all the good advice I can gather and hoping for the best from this Colt.

    The +5% spring is designed for the McCormick/Devel 8-round follower and doesn't play well with the standard follower. If your magazine is a standard 7-rounder with the flat, dimpled follower, what you need is the Wolff 11-pound (7 round) spring. Or...if it's a 6-round OM-length magazine, the same spring.

    If it's just the one mag, throw it in the round file and cut your losses.

    It's a good magazine. It just needs a proper spring.

    Still fiddling with this. I see what you mean by
    In the working mag the follower leg engages two coils of the spring and it cannot tilt. With the Wolff/CM +5% spring it only catches 1 coil which allows the follower to tilt.

    It appears that Wolff does not offer that 11lb spring anymore? Here's the page, tell me if I'm missing something?

    Here are the two springs

    20200914_175949.jpg

    In the magazine the left follower only catches one coil down from the top. On the the right the follower catches two coils down from the top. Where can I get more of the spring on the right?

    I'm thinking the same thing!
    16 coils on one and 26 on the other:confused::confused::confused:

    I have a 45 Auto Kimber Ultra Carry II that I won and have 7-round flush-fit Kimber magazines as well as 7-round Wilson Combat magazines for it. So far I have had no problems. What magazines would you suggest for the best reliability in that pistol?

    I generally use Checkmate 7-round flush-fit magazines with hybrid or GI feed lips and dimpled followers in my Government and Commander-size pistols.

    The question has answered itself.

    When he spring and follower are installed in the magazine, three coils bear on the rear leg of the follower. One in the upper corner, one near the center,and one at the bottom.


    I'm not aware that they've discontinued it and couldn't imagine why they would. I'll check the link you provided.

    Edit to add:

    This one is probably the 11-pound spring...10% over the design standard of 10 pounds...so it's at least a 10 pound spring, which is perfectly acceptable. It just won't last quite as long as the 11-pound spring.

    7 ROUND 1911/COMMANDER & 6 ROUND OFFICERS - .45 ACP

    The thinking behind the 11 pound spring was that it would allow the the slight weakening of the spring after taking a set...which they all do...and still maintain full design strength for a new spring for many years.

    You'll probably wear the gun out before you have any trouble with a Wolff 11-pound/7-round spring.

    Good. Remember that the same spring works in the Officer's Model 6-round magazines with the standard followers.

    I assume that means that I should use 6-round magazines in my officer-size Kimber. I will try to find some. Thanks.
