View Full Version : 1911 hammer follow through
July 11, 2000, 10:04 PM
I have a Gold Cup (new version w/o the depressor, etc.) that has had a trigger job and follows through only if the gun is tilted downward from horizontal. This, BTW, is on a live round or snap cap.
What is going on here? The sear looks fine and seems to have the requisite .010 of surface. The hammer hooks appear to be just a bit over .023 as measured against a feeler gauge by eye and fingernail. This isn't enough from what I've read. Is this the real cause? Also have a tiny bit of intermittent creep.
Some additional info is that I have an aluminum trigger, a four finger Clark sear spring, an 18.5# recoil spring (no guide rod), and a reduced power mainspring (Colt green). Additionally, the series 80 parts have been replaced with a shim.

B, hammer follow is usually the result of tool little sear engagement combined with too heavy a recoil spring. Even a trigger pull as heavy as 4# can have hammer follow eventually if a heavy spring is used. I recommend you have a trigger job done on the pistol. If you don't have anyone near you, feel free to e-mail me. George

The amount of hammer hook engagement (.023") seems fine. The angle of the sear nose and/or hammer hook may not be correct. It's hard to get it right without a jig. It's also possible that the sear spring doesn't have enough tension & is allowing the trigger to float back as the slide slams home, in effect, pulling itself. This would be corrected by slightly bending the center leg forward to apply more tension/resistance to the disconnector & trigger. Sometimes the left leg of the spring will also need adjustment.

I paid to have somebody with a jig do the job right. It only does it when nose down 30-45 degrees or more, but this is a real-life angle if reloading, so it must hold, in my book.
Is 18.5# too much spring? I want something that will stand up to +P.
I'll try bending the fingers.

I guess I have to wonder why you don't take the pistol back to the guy that did the trigger job and have him do it correctly. Isn't that the correct option?

B/C if I can do something this simple, it'll save a drive. If it doesn't work, then I'll make a trip.

IMO, this isn't an area for the untrained to be tinkering with. When I pay for work, I expect it to be done correcty.
Note that I don't always get what I expect... :)

Try increasing tention on the spring as mentioned eariler in the thread before doing anything else. It may just solve your problem. If it is not 100% after adjusting the spring, get it looked at by a professional. John K
