Hoping some one here can help me out.
I sold an almost new Para to another CGNer, it is a LTC 9mm 1911.
The gun had only been to the range once when it was bought and then sat in the safe for over a year which is why I sold it.
Total round count was probably around 100 and then gun worked great and was very accurate.

The new owner took it to the range and put 160 rounds through it and has reported that the gun is very accurate but the last shot on every mag misfeeds.
He says he has tried loading less then a full 9 rounds in the mags anywhere from 1-8 and they still misfeed on the last round, he is using both factory and reloads with the same result.
He says the mag springs feel like they are worn out which is not possible, the gun was purchased new from a local gun shop and the mags were stored unloaded.

Any suggestions would be greatly appreciated.

PLEASE, leave out the negative drivel and off topic comments and lets stay focused on topic.

Thank you in advance for your help.
 
9mm 1911s can be finicky. It may be an ammo issue. I find round nose runs best in these guns and can have issues with flat nose or hybrid ammo shapes.
 
Using 9mm round nose reloads and factory. Both types work fine in Glock 17, Sig 226, Sig 2022, XD9 and Jr carbine.

Last round does not feed out of mag, and gun goes into slide lock. This happens constantly whether there is one or nine in mag.

My observations: With one round in the mag, the follower is pushing on the slide lock. This seems to be forcing the gun to go into slide lock with one round left in the mag.
It baffles me with a gun that has had 100 rounds through it that both mags do it. I have not taken the mags apart yet, but it would be hard to believe I have to replace the springs and followers. Especially since it happens with both mags. I do not have any other mags to try in it yet to rule out mags.

I had a buddy shoot it as well to rule out user error...

The gun shoots like a dream! I love the gun, I can accurately hit everything I aim at. Groupings are great.

Mag springs in right?
 
sounds like a small adjustment required to the MAG where it contacts the slide stop/lock... bending or removing material until it doesn't lock with one round still in the mag..

a more permanent solution is to grind the contact surface on the slide stop/lock so it works with your mags AND other mags

my 2 cents from my own issue with a 1911 in .45acp
 
ezine.m1911.org/showthread.php?91-Ruger-SR1911-Review (picture for caption below is halfway down page)

The SR1911 was very comfortable to shoot, based on 400 rounds spread over several sessions by two shooters. There were five malfunctions recorded: three failures to chamber, easily cleared with the classic “tap/rack/bang” procedure. The remaining two malfunctions were premature lockbacks.

The failures to chamber were experienced with two rounds of Speer 200 gr Gold Dot JHP, and one round of Winchester 230 gr SXT (ex-Black Talon). The latter was a duty round that had been chambered and ejected numerous times and thus could be considered “junk ammo.”

The premature lockbacks appeared to be caused by the excessively long slide stop lobe combined with the weak plunger spring. Clear brass markings could be seen on the lug.



just one other possibility.. but I would try bending the mag follower contact lip, or grinding if it's the plastic follower with the notch.... YET, it seems weird that it could be off so much that it would still lock back at the depth of one whole cartridge. That is why I posted the above link

If the plunger spring is weak, and the slide stop is already a very close fit or has a big 'lobe' as they say, even a bullet could be pushing it up, as is evidenced by copper/lead line on that inner lobe... as it would have little resistance to the nudge :)

Msg spring tension isn't strong enough to push the round up and hold it in place when the slide tries to strip the round. I bet it is causing a nose dive right?
 
Original mags, I have not taken the mags apart, so I do not think the springs are in wrong.

It could be mag spring tension. It looks like the the 2,3,... rounds are not pointing the nose of the bullet up and the follower may be tilted down on the front a bit.
I did not want to stretch the springs of the mags until I was certain, especially with such a low round count.

The follower is plastic, not sure if grinding any material will not make it too thin. Strange that 2 mags doing exact same thing.

9mm bullets, they are not hitting the slide stop. they are a lot thinner than the .45 pumpkin throwers.

Plunger spring seems like it has tension when putting slide stop back in, the slide stop is not hard to move though. The mag follower moves the slide stop easily. There are no detentes on slide stop where plunger spring contacts it. Not sure if it is supposed to have any. Can the plunger have been put in backwards? Is it possible?

I am looking for an extended slide stop, but I am having trouble finding one. Is there any place up here that is well stocked on 1911 parts? 9mm 10 round mags are hard to find as well, nobody I know has any in stock.
Can the plunger spring be stretched or will I have to search that part down as well?

Maybe I can try the EE and see if anybody has spare parts kicking around.

I really like this 1911, I do not have a problem if I have to find parts to customize it, just not sure what to get and where.
 
Mags make a big difference.

how many ard you looking for? I may have some wilson ones kicking around.


Your slide stop should not be touching the bullet. That's your problem.
