Series 70 govt Model trigger hang up

p0838

I have a 1976 Series 70 MKIV Govt model. Functions flawlessly. However , Ive just noticed that when the hammer is half or full cock and the slide pushed back a small amount as to push the disconnector down, when pulling the trigger, there is a slight hang up before the trigger goes all the way. The hammer does not fall ,which is correct, even after numerous trigger pulls with the disconnector down. There is never any trigger hangup with the slide fully forward What's causing the trigger to temporarily hang up when the disconnector is down??[This message has been edited by p0838 (edited 03-28-2002).]

The disconnector is the disconnector. It is the piece that disconnects the trigger from the sear after the shot is fired, so the trigger will not cause the sear to be tripped again and another round to be fired without another pull on the trigger. All semi-automatics have disconnectors, or they are full-automatics!I think what is happening when the slide is pulled back enough to activate the disconnector, is that the disconnector may be just a tad short so when it is "disconnecting" the trigger from the sear, there is slight contact between the parts, causing the feeling you describe.

Judge Colt: Contact between what parts?? I cant be hitting the disconnector with the trigger because it would trip the sear. Correct???

Like Dr. Pig, I too wonder why this exercise, but I will mark it up to intellectual curiosity.Apparently, the poster is not familiar with the fire control mechanism of this most common of pistols. The trigger is not hitting the disconnector to give the feeling described, but rather the disconnector is hitting the sear. (The trigger pushes on the disconnector at all times, which is either "connected" to the sear by its position up and down, or "disconnected" from the sear.) The hammer will not fall at half cock because it is held by the half-cock notch. At full cock, apparently not enough of the sear is being engaged to trip the sear. It instead slips past, giving the feeling described.Depending on how far the disconnector is pushed down by movement of the slide, a small portion of it still engages the sear if it is not completely depresesed. By moving the slide back and forth a small amount, the condition described can be induced and removed, depending on the up-and-down position of the disconnector, which is controlled by slide movement. (The "half-moon" cut in the underside of the slide is what pushes the disconnector down and allows it to be pushed back up by its spring.)If this explanation is not clear, which it may not be to someone who is apparently not familar with the fire control mechanism of the M1911 pattern pistols, take out the grip safety and reassemble the pistol so you can see the action and relationship of the sear and disconnector as the trigger is pulled with the slide in battery, and with it partially out of battery so as to cause movement of the disconnector. Are we clear on this now?
