1911 feed problem
 
I am having a feed problem with my very standard Springfield 1911A1 [9mm]
I am sure someone out there can help me.
I load my own ammo and am happy with it. I use 4 different brand mags and am having a feed problem with them all.
when threatened with a 'tap, rack and roll' a tap will usually result in the next round feeding in ok.
It seems that the mag is not sitting quite high enough. It has about 1.2mm
[0.050"] or so free play. Is this as per spec or should I be looking at something else.
I would like to inspect the mag retainer, is it ok just to remove this with the gun completely assembled?

thanks team

Welcome to the FTF. Please check into the "Introductions" area when you get a chance.

Now, on to the problem. The normal feed sequence is the round will go up the feed ramp, hit the top of the chamber, then line up to go in. On the cheapest mag, try opening the lips a little more, and see how it does. Use needle nose pliers and go slow. The 9mm mags are pickier than the .45 ones.

The mag retainer (really, magazine release) can be removed without complete disassembly. If it has the flat screw head, try to (gently) "unscrew" as you push the mag release in. You will feel where the lug will go into a slot. The "screw" will turn counterclockwise about 90 degrees and stop. Then the mag release with come out.
But I do not think that is the problem.

Keep us informed.

i will give it a go with one of the kkk mags i have. these 10 rnd mags have never ever reliably fed the first 2 or 3 rounds, should have gone with all shooting star mags as these have proven most reliable!!

I'm a far cry from being any sort of a gunsmith..... having said that, none of my 1911 mags have anywhere near .050" of free play. You might consider modifying your grip to apply upward pressure on the magazine base, and see how, or if that affects your feeding issue.

thanks for the input. Tapping the bottom of the mag usually does the trick.
I am going for the mechanical side of things first as all mags are seemingly giving the same problem. I am sorta hoping that it is something to do with the mag release...... will see tonight

Get another mag release from a friend (the .45 and 9mm are interchangeable, in mine anyways). Even without going to the range, you should see a difference if that is the problem.

had a look at a friends 1911 .45 and the mag freeplay is about the same [about 1mm, after re inspection mine is about that.
took the mag release out and cleaned it , yeah it was a bit dirty.
wasnt much better on the range on sunday though. the general consensus among the wise elders, [ i always like to take any advice onboard] was to shorten to loa of the round by .5 to 1 mm. that will be down from what i am running now [28.5 - 28.6mm], anyhoo we will see......

I'm sorry, I should have picked up on that Overall Length before when you said that you reload.

1911A1 9mm feed problem fixed??
 
well the shorter round seems to have done the job.
I put 150 rnds thru in prac pistol last weekend with only 1 misfeed
so 27.6 to 27.8mm seems the go, i did however break the golden rule and changed 2 things as I had to use round nose projjies [at 135grain with 3.6 to 3.7 grain AP70N powder]
I will be re loading another 150 or so this week for the coming weekend hopefully all will go well.

another 120 rounds and [seemingly] problem solved..........
