The pistol is a M&P40c manufactured June 2013. The Apex DCAEK and Ameriglo SW-802 were installed by me. (LINK) I got both for $167.00 shipped from Buds. Let me tell you; I've built engines, transmissions, stereos, furniture, wood framing, and successfully completed various other hands on/mechanical endeavors... I figured this would be very easy after watching dozens of youtube videos and reading about others installs, and this was by no means as straight forward for me as it was for others.

I used penetrating lubricant overnight on the front and rear factory sights. I had to drill out the factory 1/16" allen screw because none of my 1/16" wrenches would make it budge and I broke 3/5 of them in process. I don't care about the allen keys. My concern is the pistol having a part that is not properly ANSI spec'd. I know it's just a stupid allen screw but that's how I feel.

The night sights went on pretty easily but getting them centered was another story. I made my own sight punch (PIC) out of plumbing fittings from home depot which worked very well. The front sights got a little P-blaster but I would not do this to the rear because of the striker blocker assembly's location being right under the rear sight. Because I was able to clean out the oil when I changed the striker blocker I wasn't concerned with oil to get the sights off. There is really no need for oil to get the sight back on and doesn't seem like it would be of any benefit.

Taking the rest of the pistol apart is very easy, and the DCAEK install was very easy. Putting the pistol back together takes a little bit of wiggling things around but if you're any bit mechanical it's not bad.

If I were to do another install, I would 100% purchase a sight pusher, and brass punch specifically for pistol roll pins. For my pin pusher I used the S&W punch that mounts at the bottom of the grip, which is too hard and leaves marks on the roll pins. I would also skip the Apex DCAEK. My apologies in advance to all the people who feel that this is a night and day difference for the pistol. I would rather have modified the factory parts and polished them myself than spend $90 shipped for the kit... However, the Apex aluminum trigger seems like a worthy upgrade. Just my thoughts.

Yes I should have mentioned that. Three times with a 50W soldering iron held right on the bolt long enough to get the surrounding area warm to the touch, without approaching a searing temp. Did nothing. Tried a handheld propane torch for a split second, and then 2 seconds and it didn't help. So I took a moderately powered cordless to it with a sharp bit and marked the bit a hair shorter than the depth of the sight, and very carefully drilled the bolt out. I have even read of people putting the slide in the freezer overnight, which will cause the metal to contract. But I am impatient.
 
Check out my thread in the notable threads index re M&P sight removal/install. The subject pistols are Shields, but thje same applies to the FS and compacts.
 
Awesome post. I thought you built that sight pusher yourself. I'm going to build one that's pretty similar.
 
The soldering iron did not work for me. I have a HD 200 watt soldering iron, and it got the sight area hot, but not hot enough to loosen the set screw. A propane torch took about 5 seconds and the screw came out easily. S&W uses the permanent thread locker, which takes around 400 degrees to loosen. I hold the slide upside down and since heat rises, I put the tip of the flame cone on the set screw, and the heat will rise up into the set screw.

Also all sights are mechanically pressed in at the factory. Some are very tight and I have read posts of people breaking their sight pushers, trying to get the sight out. My Shield's sight was very tight and I had the slide firmly mounted in a bench vice, and it took many hard blows with a hammer and punch, to get the rear sight to move. I have read other posts where the sight almost fell out with the set screw loosened. My sight was almost as hard to reinstall, and I greased both the dovetail and sight.

Indeed, I did build it myself, along with hundreds more like it. Good luck with your build. Not quite as easy as it looks, but with the right equipment you can certainly come up with something that will work. You can buy a half assed copy on eBay for a lot less than these cost, and probably cheaper than you can do yourself.
