Sig 1911 Grip Safety not reset

Recommended Posts

I just bought my first 1911, a Sig 1911 Stainless Elite 9mm.  It has an ugly 7lb trigger so I fieldtrip, bent the sear spring and polished the internal to get it to 3lb (thanks for tons of tutorial on Youtube).

 

Today I brought it to the range for the first time, after the 1st round I found the grip safety remain stuck as engaged position (ie, not bounced back) however the trigger can not be pulled.  I tried different tricks and then I found, I can push the mag up a bit (though it's already firmly sitted) and I do hear a small "click" and then the grip safety release so I can grip and press it again to fire the next round.  But I have to repeat it every time to fire a round.

 

I also tried dry fire without the mag in, then there is no problem at all.  I pull the trigger, move the slide back and forth, I can still pull the trigger while keeping the grip safety depressed (I don't need to release it and depress again).  

 

Anyone has any suggestion?  Thanks.

You put in the sear spring incorrectly. You didn't let the grip safety leaf of the spring, sit under the grip safety tab. You also might not have had the little tab of the sear spring sit in the notch in the mainspring housing. Sometimes happens if you try to insert the sear spring without removing the external safety. Not that you necessarily have to remove the thumb safety safety to insert the sear spring, but it requires some manipulation to make sure it's inserted correctly.

Thanks but the sear spring is well seated.  Plus, when firing after first round, the trigger can not be pulled even the grip safety is still depressed.  

 

 I think it might be the trigger bow stuck with the grip safety caused by strong forces (firing).  And that’s why dry fire can not duplicate the issue.  And also why push the mag up a bit will do the trick because the mag touches the trigger bow and loosen the stick.  I examined the trigger bow and found it’s slightly out of shape as I might bent it when polishing.  The bow was tight so the mag can not fall freely when released.  I restored the trigger bow shape but I have to wait till the next range visit to test.  Will provide update.

Can you please share what you have work on?

I know how to turn a 70 series, but I have not work on a 80 series before.

Like to get some ideas before I start.

3lb is what I need for now. The trigger is not bad, just weight too much.

 

I am working on a Sig too.

Thanks.

You may have reduced the tension on the trigger return/disconector leg of the sear spring enough to now have a small drag on your trigger bow touching the magazine keep the trigger from returning. you may be able to refit the trigger bow so that it has no contact with the magazine and slides freely in the frame and keep the lighter adjustment on the return leg or you may need to do both.

 

There is a lot going on in the ignition system of a 1911 and every adjustment can affect more than one thing, make sure you do a full safety check after messing anything.

Problem resovled.  Went to the range and had 250 rounds through it, no issue at all.  So it's the trigger bow interfering with the grip safety when it's a bit out of shape.  The pistol is tight and smooth and I like it very much.  Only complaint is that the front sight is a bit bulky and I'm not sure it's suitable for target shooting.  Anyone has any experience switch to a thinner front sight?

I do take the 80 plunger and the spring off from the slide, no big deal, just leave a hole on the slide and it reduce the trigger pull by 1lb.  I can also keep them andcut some coils off the spring but I choose the other way for simplicity.  I  leave the other two 80 parts in the lower.  It's in difference to keep them or replace them with a Tj spacer.

 

I use 13lb main spring (you can put a pencil in to the barrel and dry fire to see if you can get about the same height which indicate good hammer force).  I polish the where sear/disconnector touch each other, the trigger bow, and the tip of the sear spring.  I do bent the sear spring as well and it's very important to reduce the trigger pull.  I use #800 sand paper for polishing.  All can be done in one hour.  

 

I was disappointed with the 7lb trigger pull  and I feel the front white sight is a bit bulky.  I do like everything else about the Sig 1911 Stainless Elite.  Now my trigger is reduced to 2.5lb.  I use it in range only for target shooting.

Thank you very much.

I have the Max. Dawson sight make a huge different. Love it. 5.5 lb trigger out of box.

Will see if I can work it down to 3 lbs with everything in.

Can you let me know what Dawson sight you are using.  Do you have a link?  I browsed Dawson's website but don't think I could find one for Sig 1911 TSE.  The front sight of TSE has a tiny pin at the front to fix it to the barrel however I'm not sure any Dawson sight has it.  Is there a pin in your Max?

 

I think I'm fine with the white dot in the front but the overall sight is a bit thick for me.  I prefer thinner one (red fiber is even better but not a must).  Thanks
