    What's the correct way to adjust it?

    I fitted a 10-8 flat trigger into my Ruger SR1911 the other night. Had it fitted snug and smooth into the frame, adjusted the overtravel, and after reassembling the gun, the bow was coming up about .03" short of the disconnect.

    The trigger would free float until it hit the disconnect.

    What's the correct way to "lengthen" the bow?

    Any advise will be greatly appreciated.

    Hopefully some of the Pro's will chime in, I don't think there's gonna be any "lengthening" in a trigger bow. Gonna keep tabs on this thread, really interested in a solution, without buying a new trigger.

    Remove the 10-8 and install a Wilson trigger, they are a bit longer.

    I think you are saying it has too much pre-travel. Keep in mind that you need some pre-travel to allow the the sear to re-engage the hammer hooks. Since the "quack" trigger doesn't have pretravel tabs, you would need to put a drop of weld on the front of the trigger bow and adjust it so it sits a little further back in the frame. If you can find a quack trigger with the tabs, that would solve the problem.

    Here is how Jerry Keefer does it: (good luck!)

    Kruzr hit it on the head, it's the pre-travel that's too much on the 10-8. With the lack of adjustment tabs on the front of the bow, it can't set the trigger back into the frame, thus reducing the initial travel distance. Jerry's fix is a genious idea. He is a legend.

    For a flat trigger, I prefer Wilson's version that has the adjustment tabs.

    Replacing the trigger with a Wilson would be cheaper, easier & quicker for the OP.
    Unless he has access to a TIG welder.

    Also like to add that the 10-8 triggers tend to have a slightly longer bow as to try and remedy the pre-travel adjustment. But sometime it can be too long, depending on the spec of the frame.

    it's the other way around. the Wilson has the pre-travel tabs though.

    With tabs, you can always make yours as long as you need it.

    This is interesting. I was just talking to Quack about this a couple weeks ago. Should the back of the trigger bow be touching the disconnector when reassembled? The sear spring center leaf should be putting pressure on the disconnect and it should all be resting against the trigger bow, correct or not? Any good pics out there of this?

    Not for carry.

    Thanks for all the good info, folks. It's much appreciated.

    I think I'll follow the Jerry Keefer method. A small tack weld and more patient filing, I should be good to go.

    I'll most likely try a Wilson flattie in the future, but at least one more 10-8 is in the cards for my EMP.

    took the words right out of my mouth... How much pre-travel before the trigger bow touches the disconnector?

    A Cylinder and Slide long, solid, match trigger works for me... JMO Ron

    You know you can cut your own tab in the trigger in about 10 seconds right guys? Super easy and works like a charm.

    I like "super easy"... makes perfect sense.

    Thanks for keeping an eye on us, Joe!

    LOLOLOL! No I'm serious...I'll take a pic tomorrow when I do one in the shop to show you guys. Most of you probably already know how to do it but for those that don't perhaps it will help.

    Joe... I was serious too... as soon as I read your advice, it was one of those "Duh!" moments. Super easy and makes perfect sense.

    Was also serious and meant nothing but respect by, "Thanks for keeping an eye on us, Joe!"

    I checked pics of tabbed triggers on the internet last night, and inventoried my cutting wheels this evening after work.
    I'm fixin' to cut tabs this weekend, but will wait for your pics.
