Hi all -

I recently bought a Taurus PT1911, and the only issue I have with it is that one of the factory mags somehow always causes the last case to eject rather weakly, almost vertically.

I ordered a pair of McCormack Super Mags.
One of them does essentially the same thing each last round.

The other two work fine, so seems it's not a prob w/gun or ammo.
They do eject, so it's a problem more because the hot case usually falls on my head, hands or arms - n.g. in a serious situation!

I could buy more mags and hope for proper function, but I feel sure it's a matter of a small adjustment somewhere.

Anyone have similar experience, thoughts or a fix?

Thanks.

regards,

Sounds like something on the follower is catching the case on the way out before the ejector can engage. Cycling the action manually, can you see where the case is hitting the follower? A little polishing might take care of it. Also, make sure the followers arent' catching on anything in the magazine body.

Make sure your extractor is engaging properly and not losing its grip on the rim at any little bump.

Otherwise, Wilson mags are outstanding.

The problem is in the extractor and the ejecter. The proper fix is to increase the tension on the extrator and to change the face angle of the ejector. The case is saging away from the breach face upon extraction, this is not allowed to happen when a round in in the magazine.


Wison magazines have always fed well for me, but I do not like them because after a while the plastic follwer will not lock the slide back on the last round

Quick check- load a round, remove the magazine, fire. Repeat a couple of times. That will tell you if it's the magazine.

Good idea to run some hand-cycle tests w/the offending mags v.s. good ones.
I'll post results later.

jwp475 - the MCM's were recommended to me over Wilson for that reason.

The other pair of mags don't exhibit the prob, so thinking it's a mag issue, not ejector/extractor, right?
But I'll try the single-round test also.

Thanks.

Nope not the magazines, it is definately the extractor allowing the case to drop in conjucntion with the ejecter is the problem BTDT

sounds like the last bend in the mag spring might be sitting at the wrong angle, pushung the follower out of correct position.

Compare it to other mags via it's front and rear follower pressure with an empty mag.

 

[Rigby275]

jwp - but why would the other 2 function properly if the extr/ejctr is the prob?

digisol - comparing empty heights of the followers & lip widths w/calipers best I can, each pair seems to have dimensions within .010ish, which I'd think would be mfrg tolerances.

Still checking things, tho'.

Thanks.

 

[jwp475]

That extra .010" may be just enough to not allow as much sag in the case under extraction, and allows normal ejection. Tighten the ejector and magzine no longer matters. It will allways be hit and miss with magazines if the real problem isn't corrected

I would think it could have something to do with the follower on the mag that isn't working? Just an idea......

Here's a link to give you some ideas on fitting an extractor.

 

[Rigby275]

Well,I swapped followers within each pair, loaded & fired single rounds in each and the previously problem ones only vertical ejected ~1/2 the time.

But the previously good ones do it ~1 outa 5.

I ckd the extractor according to sionaprhys' link above and it's ok.

Thanks to all for the input so far - still looking tho'.

jwp - tried to call yesterday w/no luck - I'll try this evening.

Not to question your shooting ability, but could you be "limp wristing" during those shots? If you are not supporting the gun properly some of the momentum of the slide will be used up if you let the gun move too much. I have noticed when introducing newer shooters or even more experienced weaker shooters tend to have different ejection.

For example with both by Springfield 1911 and my Glock 22 I get strong ejection, but when my wife shoots the same guns, especially the Glock, her empties tend to land on the slide or near her hands. I have noticed that myself when shooting weak handed or while trying to hold a flashlight, if the gun is not supported properly it tends to not eject as well.

Since you have been trying magazines and ejectors maybe the next time you are at the range try to be really alert of your grip on the gun. You could also try having some one else shoot it that has a lot of handgun experience. Just my .02.

 

[Rigby275]

Thanks for the reminder, colohunter - shoulda thunk of that possibility m'sef.

While normal ejection path is variable - 8 to 12 ft, 3:00 to 6:00, with ~ 60% 10'-ish @ 4-4:30 - that this happens only with every last case from 2 of 4 magazines (before the parts swap) leads me to think not.

However, most of the shooting has been benched chrono/accuracy testing, not concentrating particularly on grip, since I got the 2nd pair.
But, having my range in my front yard, when the current rain system moves thru, I'll shoot some more single-loads focusing on grip and be sure.
