Help with 1911 issue WITH VIDEO

[JatCarver]

I bought a old Para 1911 from my uncle just to keep it in the family. He used to shoot bulls eye with it and it was the first pistol I've ever shot so has some sentimental value to me. 

 

Anyways, has a weird issue, when I pull the trigger and drop the hammer, I have to let out the trigger before I can rack the side, the slide just hits the hammer and stops. If I let out the trigger then I can rack the slide rather easy. 

 

Video of the issue...

 

 

 

I know my way around 1911's somewhat but thought I would ask here before I dive in encase its something obvious. 

 

Thanks in advance.

Have you actually shot the gun? Based on what you're showing, the slide wouldn't come back when fired, as long as you kept pressure on the trigger.

Is there some sort of firing pin safety released by the trigger? If so, it may be the push button under the slide is missing, and the the firing pin actuator on the trigger, protruding up through the frame, is going too far up into a hole, and blocking the slide from moving back, until you release the trigger.

No, haven't shot it in fear of breaking something. I just assumed it's a series 70 fire control...

 

I will tear into this and see whet I can find.

 

Thanks

I agree with Bob.  I can't think of anything else that would cause that condition, except a Series 80 type FPB that is missing the plunger.  Brownell's sell spacers that can take the place of the FPB parts inside the frame to eliminate the part that is rising up and blocking the slide from retracting when the trigger is pulled.  

 

OR, you could simply buy another spring and plunger to install in the slide.  That will keep the Series 80 plunger lifting mechanism from going into the plunger hole and blocking the slide.  

 

I also agree that you probably shouldn't fire the pistol until this problem is solved, because I can certainly see damaging parts during recoil.  

 

Here is a link showing you the Series 80 parts:  https://www.youtube.com/watch?v=i6H1tUP6IwM  At about 0:58, it shows the part that is rising up when the trigger is pulled.  If the plunger was still in the slide, it wouldn't be blocking the slide from rearward movement.  The plunger in the slide (which must be missing from your slide) is shown at about 4:10.

your thumb safety  came  up   1 -1.5 mm  after hammer hit the firing pin during  dry firing.

if u will hold thumb safety with your thumb it will never happens.

I'd bet the series 80 lever is catching on something. Have you taken the slide off to inspect the series 80 levers and plunger?

Is there any difference if you keep your thumb on the safety lever?

sometimes it can go up from   vibrations and block lower corner of the slide . there is many solutions to prevent this.

[Postal Bob]

If the thumb safety was moving up only 1mm, it wouldn't be enough to lock the safety into the uo(safe) position. And working the slide would probably cause the safety to move back down(off).

More likely is something with the series 80 levers. Especially since it was mentioned his uncle was a bullseye shooter. Disconnecting, or removing the mechanism, would allow a more precise trigger feel.

Is the series 80parts still in the gun? If yes check

Is the firing pin plunger present 

if no, then what may be happening is the upper series 80 arm is going into the plunger hole and stopping the slide from moving
