What trigger pull weight are you getting on your APEX Flat Faced FSS Trigger install?

[falconman515]

So I installed my new APEX Flat Faced FSS Trigger kit and put in the lighter silver spring (not the heavier duty green duty spring) on my M&P9 Pro Series CORE 5"

I am curious what the average pull weight most are getting on this? 4lbs. on average? less? more?

I read conflicting pull weights throughout websites saying you will get a 4lb or 5lb trigger pull based on your spring installed.
But then other sites and APEX also states on the announcement for this trigger it says the same "4-5lbs. depending on trigger return spring" ... BUT the actual product webpage for this states "Trigger pull weight between the 3lb and 4lb mark (Dependent on trigger return spring installed)"

So what is it? with the lighter silver spring should I be getting a 3lb pull or a 4lb pull???

Curious what everyone else is getting on their install?

Thanks so much

I don't have the flat faced trigger but I do have the curved aluminum trigger and FSS kit in my M&P 9mm full-size. Trigger pull dropped from 6 lb 3 oz to 4 lb 8 oz.

I am getting 4lb 7oz. Also have the Competition Kit in the 9 Pro L. I was hoping for better as it is my target gun. Don

Here's how mine measure up:

These all have the flat face kit:
pro series 9 runs 4lbs 5.4oz average over 5 pulls
My Performance center 40 runs 4lbs 5.2oz average over 5 pulls
My shield 40 runs 5lbs 6oz average over 5 pulls

My 40 pro series has the competition spring and sear kit with the stock trigger and it averages 3lbs 10oz

Edited to add that this is measured with a Lyman digital pull gauge

SO here is the deal and updated info that I have learned since my OP

I spoke with John the lead designer at APEX (VERY cool guy and TONS of information on their product and willing to help me in anyway possible to get me the right pull weight ... even if he had send me a new spring set etc. he said).

So to answer my original question why I see on their announcement it says 4-5lbs but their description of the product says 3-4lbs.
When announced they were not done yet and basically kept it attainable in their announcement information of 4-5 ... But once completed and ready for sale they were able to tune it to on average get 3-4lbs. based on the spring used. So that's why I see this info and he answered that.

I was getting on average on my M&P9 CORE with the silver spring installed about 4lb 2oz. ... and knowing that this is the spring that gives me the lowest pull weight I was "okay" with that but would like to see something in the 3-4lb range if possible.

SO if are getting the 4 to 4.5 range with the silver spring installed and want to get less then 4lb. pull weight ... Install The STOCK trigger spring!
Ya I was kinda like ... Huh?
He said if you are getting that 4.5lb. type pull then if you install the stock spring you will be under 4lb. no matter what.
He went into explaining and it kinda went over my head really.

Went home last night and pulled it apart again (cause after you do this once you are pro every other time after that) and took off the Apex silver spring and put back on the old stock S&W spring and put it all back together again.

3.5lbs. DEAD ON almost every pull ... in fact with the stock spring the average was much tighter and did not move around as much and really hit 3lbs. 8oz. almost every damn time.

It breaks CLEAN! Now I'm kinda worried it may be too light ... but it will be used for target and comp. type shooting so shouldn't be a biggie ... not a carry pistol at all.

John at Apex was VERY cool and said he is willing to do whatever they need to do to get it right for me and send a different spring, different sear, etc. to make sure I get the wight I want.

I wanted 3.5lbs. and I got that with the stock spring ..... But I know if I want a touch more I can throw the silver back on to get back up to about 4lbs.
So in the end having both options I am very pleased with the weight and this flat faced trigger.
Dry firing is AMAZING over the stock M&P trigger (but let's be honest most all triggers are better then these).

Figured I would give this info here in case someone in the future may have the same questions and find this thread.

Don't discard the stock spring as that seems to give you a lighter trigger pull if desired come to find out.

Anyways thanks for the info and help guys ... I hope this info I provided helps some as well.

I am getting 4lb 7oz. Also have the Competition Kit in the 9 Pro L. I was hoping for better as it is my target gun. Don

Magload if you are getting about 4.5lbs. on your 9L try putting your stock spring back in ... I bet you get below 4lbs. with it.

"The spring" = the trigger return spring, not one of the others (sear, striker block, striker)?

Yes sorry ... I didn't make that known.

The only spring I was talking with him about and replaced back to the stock spring was the Trigger Return Spring (spring on the trigger pin connected to trigger bar).

Great info falconman, I installed my first flat face kit right after they came out and like you questioned the pull weight. When I talked to apex they sent me a new spring set and there was no difference so I just figured it's the way it is. I'll be putting the stock trigger spring in mine to see what I get.

Let us know the before and after ... I'm curious if the same thing follows to others that are above 4lbs. after installing the stock trigger spring.

3 lbs 9.8oz as measured with Lyman digital gauge on 10 trigger pulls average. All Apex parts with silver trigger return spring and nothing polished.

I am also in the process of upgrading my stock trigger to the Apex Flat-faced trigger and was told to also use the Apex Competition Spring kit to further reduce trigger weight by approximately 2.0 lbs (based on a starting trigger pull weight of 7.0 to 8.0 lbs)

I use the flat faced trigger but not the competition spring kit. I've also done some polishing on various surfaces. This is what I ended up with. I've used this gun all last season (1-2 matches a week, 3-4 practice days a week). Never had a ND (or AD depending on which you prefer ). I did experience a broken trigger (in the pivot area), but I'm shooting 9 major so I kinda expect breakages.

Finally changed back to the stock trigger spring. Here's the before and after:

Pro series 9L before 4lbs-5.4oz, after 3lbs-11oz
Perf. Center 40 before 4lbs-5.2oz, after 3lbs-6.1oz

These are 5 pull averages

 

[falconman515]

Ya it's weird how the stock trigger spring gives you the lightest pull weight.

But it seems that the trick at getting that 3.5 odd lb. pull is to slap the stock spring in if your not getting under 4lbs.

I know this is an old(er) thread, but my results for the
Apex Flat face FSS kit is a consistent 4½ lbs with a best
pull of 4lbs 3oz. I used the Apex silver trigger spring.

Very impressive engineering in this kit. My hat is off to Randy
and the team @ Apex tactical
