Sear and sear disconnect question




Are the sear and sear disconnect the same on a GI 1911 and a Milspec version of the Springfield Armory 1911? If they are, where can you get those items? Thanks for the help...

You can get these parts from Brownells or Midway, but the thing I will STRONGLY point out is that these are not just drop-in parts. They require fitting before they will be functional and safe. If you are not familiar with and don't have the tools to do the job right and safely, i STRONGLY recommend contacting Springfield if you're having an issue with these parts and allow them to do the work for you to fix the gun right.

Del,

Other than making sure the TS engages correctly, what fitting is required for a sear and disconnector ?

The nose of the sear must be fitted to the hammer hooks and checked for proper alignment and engagement with the hammer. The gun must be checked for hammer follow. Not all sears and hammers are created equal, so the hammer must be checked to make sure it engages with the sear, I've had ones where the sear never locked the hammer in place, had to replace the hammer.

The sear nose also has to have the correct angle on it and the correct relief as the engagement between sear and hammer is not a 90-degree flat lockup.

Here is something I have been wondering. I know that a sear and hammer should be fit to match for optimal performance, but does Springfield (as well as other companies like Taurus, Remington, even Colt) actuallt fit these parts on their lower end production guns, or do they just assemble, function check, ship it out?

I have 2 Loaded Springers and neither the NM 9mm or the Imbel .45 came with fitted hammer and sear parts. You could see the machining marks on all 4 parts ( 2 sears and 2 hammers).

Go to Fusions website as you can find the parts the cheaper than at brownell's. I just finished installing a Fusion trigger kit in a Springfield Champion G.I. that includes the sear and disconnector. You have to do a little polishing on the sear surface and hammer hooks and may have to fit your thumb safety again.

If you have any questions just let me know.

Prefit kits, such as the fusion kit, or the Cylinder and Slide kit, are probably the easiest way to get as close to drop-in as you can. I personally recommend the C&S kit over fusion, but either works.

The problem with such kits are that if the pin positions are even slightly out of spec, you will need to modify the sear and/or hammer for fit. Also, you may need to polish certain parts to get them to fit in the frame.

Doable? Certainly. And a good learning experience. For safety's sake, if you're not comfortable with the process and/or are not very mechanically inclined, I still strongly suggest letting a gunsmith handle the job.

I forgot about Cylinder & Slide's kit. Lots of folks like those I just could not justify the extra $60 for it.

But if you are uncomfortable with it, send it to someone that is competent enough to do the job for you.

Thanks, that is what I thought. Also answered my question about fitting on the NM guns.
