Not good... MGC Colt 1911 Firing Problems

Ok, Ive had this gun since Friday, and i just got some caps...put three rounds thorugh, one at a time and all 3 times the slide failed to lock back...any ideas??

Thanks,

Jeremy

The slide doesnt even go back far enough to load another round or cock the hammer...why??

Any help??

This is a new gun, and I shouldnt be having this problem...I dont know much about gun internals, and I really dont wanna take this thing apart without knowing much...airsoft guns were one thing, but I dont wanna mess this up.

I just want it to work!!

I think the best thing is to go through all the problems that can happen even if they seem obvious, first which model of MGC 45 do you have as there are several versions is it new type real size round or older smaller ones. does your slide move freely if you manually rack it, how exactly are you loading your rounds. lets strat there and if we cant cure the problem form that we will continue.

Hey thanks for your replies!

I lubed the slide with slicone spray...and then loaded the cartridge, primer, cap, and couldnt find silicone grease, so I used the spray on the o-ring...would silicone lithium grease work?

I cant really tell if the slide is moving freely or not when I manually rack it, I have no problems when I rack it...but, it seems like it hangs up a bit when pulling back if Im not putting enough pressure on the grip safety. But if I wasnt putting enough, I guess I wouldnt be able to pull the trigger.

It fires, ejects round, loads another, but hammer doesnt cock...or slide wont lock after last round. Obviously the slide isnt going back far enough...

Dont know what else to do...unless trying the lithium silicone grease is what I need for the cartridges...

Also, Im not sure if this matters, but Im using the only caps I could get here in the states...M.G.Caps 7mm yellow/white box.

first you dont need to grip the grip safety to rack the slide thet grip safety is only for when you pull the trigger so if the slide is feeling stiff i think you need to take the gun apart and check the inside. the only thing i can think that would cause you problems is the cam which could be the wrong way round which would cause a problem with the slide. any chance you can video it firing and you manually racking the slide looking at that may give us a better idea, the other thing exactly how are you loading your rounds, most lubs will work fine for the O ring seal i use silicone and a light oil depending on which gun i fire as some work better with one than the other but if the seal is clean then on first firing the grease is notthat important.

What and where is the cam? Everything seems fine with the gun...I just dont know how it could not be lubbed enough...and how could parts be on wrong, if its a new gun...this doesnt make sence to me...at all!!

First off relax Modelguns are very different to other types, thats what makes them frustratingly beautiful!
Part of the beauty is understanding and fixing them so they work as you want. But take you time!
(tempted to make English joke here about "fixing a modelgun is like making love to a bueatiful woman") LOL

The MGC is a great model so the problem cannot be that bad, something simple.... First you must learn to strip the gun, without being able to do that you will run into lots of problems, and it is something you should know how to do first before going any further.
So strip it and check all seems roughly as it should inside (google colt 1911 field strip for guide, its pretty dam close to the real gun, so lots of info out there:))
Then clean everything (carts must be spotless inside the o-ring sliding smoothly is the key)

Put it all back together again and try again:)

I cannot stress enough that even though you are frustrated now, take your time and it WILL all work out:)

PS please excuse spelling errors, rushing this!

I didnt strip it completely, but I dunno what else I need to clean to get this to work...I have it lubbed up like crazy...but whats preventing the slide from cocking the hammer??

Can I try lithium silicone grease??? Do you think that might help??

did you get the top slide off yet?
No, grease I think at this stage is not the answer

Please describe in detail how you load cartridges with caps, what happens when you pull trigger each time etc. This will help narrow down possibilities.

I load primer, cap, then firing pin after using silicone around the o-ring...the gun fires, ejects shell, but hammer doesnt cock for next round...if the slide is going back far enough for it to eject/load another round...why is the hammer not cocking??

From what I've gathered so far - it seems to be the hammer having the problem: now the hammer of your 1911 is behaving like a double-action only pistol (the hammer returns along the slide after the shell ejected)...the slide action somehow touched the trigger bar

The same happens on my Marushin M92SB so that's why I know ...

Does it happen when you manually cock the slide?

Must be OK like this as first shot can fire eject and load, key point is is you manualy cycle the slide with the trigger pulled does the hammer reset/work as it should?
Also have you had the slide off yet?

I don't think the first shot is always good - it seemed as if every shot had a problem.
Good point about keeping trigger pressed while cycling though. Do it without a cap ;-)

I took off the slide, and couldnt identify a problem...are you guys saying to hold the trigger all the way through the shot? I normally squeeze the trigger, then release...as normal I suppose...but holding the trigger through? I dunno. What other remedies for this are there? If its the hammer, would that also fix the slide not locking back?? I havent had more than 2 rounds in the mag at a time.

This is so frustrating. I appreciate your help.

If hammer does not cock after shot, this can mean:
- slide does not go far back enough to cock it
- sear that holds hammer doesn't lock on it, or releases immediately, maybe due to trigger bar interfering

When you rack slide manually this allows to see if hammer cocks at all by slide action. This serves to eliminate broken sear.
When you pull trigger AND rack slide manually this allows to see if interaction of trigger mechanism prevents hammer from being locked in cocked position.

If mechanism operates correctly, it might be that blowback is too weak to cock the hammer. It would be likely too weak to move back far enough and chamber another round though.

For troubleshooting you need to pinpoint and eliminate probable causes one by one.

I racked the slide manually with trigger pulled, and hammer did not lock back.

OK !
Now you are begining to get somewhere:)
That means there is a problem with part 21, 22 or 29 on the parts list here in the link I sent for the MEU model (I would guess same part number on your model)
As the slide moves over part 22 it depresses it which resets the trigger for next shot allowing hammer to lock back, Try taking of the slide and seeing if you can depress the part by hand (I would guess you can as slide will not go over it if it was locked up.)
It is quite a bit more stripping to get to these parts to get them out, if you do go for it then just take you time when taking apart, but can you possibly post some pics of the top of the frame with the slide removed?
