This is my review. It represents my opinion only. It is based on what I like and want. I am not a good shooter competitive wise (C or D class), but good enough to know my firearm and what I like, and don't like. I also kick Timmy's ass at the range so I am not THAT bad.
Alright so many of you are familiar with my fubar upgrade of the flat face trigger which is not production legal (one would think a competition upgrade might warn you that it is not legal in the major competitions--ahh yes caveat empor). Luckily after going full retard, I took a step back and fixed my screw up. What I ended up with is:
Standard M&P Frame/Slide
Apex Hard Sear
Apex Silver Trigger Reset Spring (it is my understanding that the green spring increases trigger pull to around 5-6 lbs).
Apex Striker Block Kit
Standard M&P Trigger.
What I received in the package (via Midway).
The Apex Flat Face Trigger Kit.
No Parts list (with multiple weight/strength Trigger return springs, it would be nice to know the weight of each rather than a google search).
In order to complete this upgrade I also got the Apex armor's block (doubles for Glocks--have a few of those around).
Rest of stuff I used:
Set of punches
Set of punch starters
New Sear Block Housing w/ 1/8'' plunger (required)
Also note that S&W only sells sear block housingings with a Magazine AND external Safety (more on that in a bit).
So i went a you-tubing and the install is fairly simple (uhh watch youtube). Punch out your pins, remove trigger, yadda yadda yadda.
I am not a gun smith. I am competent with a hammer.
Entire upgrade took about 2-3 hours going slow--chasing down springs, etc...
What this did:
lowered my trigger pull from 6-7 lbs to 3-4 lbs. (I don't have a trigger pull gauge--it is comparable to a Glock with a "-" trigger or a 4 lb 1911. (Because I pulled both of them out and compared).
Moved the engagement of the sear forward (less take up). Still much over-travel.
What it did not do
Provide positive reset after the slide cycles. Actually there is no reset--you can't tell if you have reset the trigger or not.
Overall--works as advertised. Brings trigger engagement forward, lowers trigger pull to 3-4 lbs.
Still no positive reset on that blasted junk S&W trigger.
The flat faced trigger did have a solid reset (and little overtravel), however as mentioned: IT IS NOT PRODUCTION LEGAL DUE TO THE OVERTRAVEL STOP.
S&W sear block housing issues.
Sear Block Housing Fix.
S&W sear block housings are confusing, and a PITA--they are not clear AT ALL when searching Brownells, Midway etc.. As mentioned--only one for sale is the magazine and external safety. Problem--this renders your S&W unable to fire without a magazine inserted (Gee I wonder where that might be a problem).
First if you are like me and do not have an external safety, the new sear block housing has a surprise for you. It has a safety mechanism build in that pushes the trigger bar away from the sear. The fix is simple. Hit it with a small punch and remove it. Yes I broke it. I don't have an external safety. If I wanted to shoot with an external safety I would have bought an external safety model (/end rant).
Second--the magazine safety.
The magazine safety is located on the same pin as the takedown lever/sear disengagement lever for disassembly. Simply slide that pin out. You can remove both safely (reportedly) or if you are like me, I took the spring from my old sear block housing and used it to hold the takedown level/sear disengament lever in place (the stock spring in the new Sear Block is too small). Other users report using pen springs shortened or clipped. However, I figure if you have to buy a NEW sear block housing, you probably have the OLD sear block housing, so just use that spring. Use a small punch to help guide the spring in and get it compressed with the takedown lever, re-insert pin and viola.
Bottom line--did it work? Partially (Taking a rosy view that I started with a Competition Spring Set only)
Would I recommend? NO. If you have no trigger reset and the overtravel and take up are still atrocious, you have really have not fixed the issue with the M&P trigger. Plus with 4 hours labor and assuming I just got the competition kit, I'm still at $80 worth of parts, major disasembly, several hours of my time, and I still don't have as good a trigger as my Glock with a $25 part that took half the time to install. (I hate Glocks, but dammit they work). Plus no instructions/parts list on the package--I am a diagram kinda person, it left a bad taste with me that my instructions were "youtube" (Or not even a note that said "go to www.idiotboughtwrongtrigger.com for installation instructions").
Also advertising a competition upgrade that is not legal for USPSA. Not a fan. Lets be honest, people don't use M&Ps for Limited or Open. Its a production gun. And we still have a crappy trigger, just lighter (assuming you leave the actual trigger out, but keep the internals--which is the majority of the upgrade). Thats a lot of time and money to not fix a problem. What it did give me was more confidence in upgrading my guns for my inevitable switch to something more appropriate for competition (I would shoot my Glock, but its a .45, 9 is cheaper). However at this point the gun is not holding me back. So I will stop writing and go practice.
TLDR: Apex competition kit makes trigger pull lighter and shortens uptake. No change in over-travel(lots), or
felt reset(none). Flat Face Trigger is nice, but not prod legal. Can't put lipstick on a pig. Practice more. Gear Queer less. As discussed below, reset is improved, but the forward travel is so huge it makes no difference (for me).
