M&P upgrade suggestions

That is great news! Is there any adverse effects on doing this? Thank you for chiming in

Other than a more reactive trigger, I've experienced none. I'm going on 6 years with the 1.5 build.

How about the reset? Would this somehow stall the reset as in having to let the trigger extend out more before it actually resets?

It did not affect the reset. As far as I can tell.

Ok sounds good. Ironically I just received a wheeler manual trigger pull scale in the mail and I tested the trigger. It is measuring at 8 lbs on three different tests. Do any of you guys know what I should look for? the trigger pull is supposed to be 5.5 lb

Thank you for the detailed reply. I was just simply asking if it is normal to have that much take up after the Apex kit is installed. I like the trigger pull and love the reset but just wanted to make sure I didn't install something incorrectly on the innards. I have a Springfield operator 45 ACP 1911 which I love and it is completely stock except for the grip. What kind of things are you guys doing to the 1911s to tune them? Sorry if this is a ignorant question, I have been shooting guns for almost 40 years but I am definitely not as seasoned as most of you on here

I will radius the edges of trigger loop and then polishing it well .Polish the sides of the sear and hammer . Do not touch the engagement surfaces of the sear or hammer as most are MIM parts and not the hard part . nd to swap out the 23 lb main spring for a 20lb spring for 230grammo or even a 19lb spring for 185 to 200gr bullets .I do not use +P ammo so recoil spring can stay the same . Tune the sear leg,,,, Cylinder & Slide sell a Light sear spring that is said to reduce trigger pull by 1.5lb's ! This may cover your needs . Or buy a several new colt replacement sear springs to tune as its easy to muck one up !! Don't ask how I know this to be true .

Now to tune a new sear go to you tube or 1911 forum and wlook for info to bend the spring slightly for a lighter trigger pull But you can get it to light and then throw that spring away . Leave your stock spring alone so you have a good spring to use if needed .

If you have acess to a digital trigger pull gauge harison Design has good directions to work with for tuning a sear spring .

The 2.0's don't use the "loop" on the trigger bar. They use an "activator" to drop the sear. The "activator" is highlighted in red. The trigger bar pushes (green arrow) to rotate the sear and release the striker.

So the trigger travel before the wall deactivates the striker block. With Apex's forward set sear (FSS), the activator has an extended tab (in red) that shortens the distance, thus reducing the "pretravel".

Here's the 2.0 sear housing. The activator elements have a red line. The green arrow shows where the trigger bar would sit and move the sear when you press the trigger.



This is the activator with Apex's FSS kit. Note the red block showing the extended tab.

Thank you for all of the information. I actually didn't get the Apex FSS flat face trigger but maybe I should have. I used model 100 - 126 action enhancement duty carry trigger kit and I utilized the stock activator. I am measuring 8 lb of trigger pull so I'm not sure what the heck went wrong. Any suggestions on where to look? I'm supposed to be around 5.5 lb which is a pretty significant difference
