M&P Apex Tactical install

Thank you

Thank you for all the help. I appreciate all the input. All replies are very helpful. I am going to invest in a vice, and will get the sight pusher tool. I am going to get all the proper punches. I will try to watch as many videos as I can, and get familiar with disassembly/reassembly. I will purchase my first kit next month and give it try.

Thank you

I've done 3 of the FSS kit installs: 1. Aluminum curved trigger version on my CORE, 2. Aluminum curved trigger version on my wife's FS9, 3. Aluminum flat faced trigger version on my friend's FS9. In fact, today I switched out my curved aluminum trigger for a flt faced version.



As others said, watch the videos a few times. The Apex video is OK, but will jump in the part where you assemble the trigger, slide stop, slave pin. Other points:

• Be careful of the take down lever retainer spring in the trigger block. It looks like a small bent staple. It comes out easy. Keep an eye on it when installing the block.
• The armorers block is great, especially for the trigger bar pin (however, it does not work for the flat trigger - at least my older version block doesn't)
• Test fit your sear block before trying to install it with the trigger bar so you understand how it fits in the frame
• Be careful of the ejector as it can come off easy during install of the sear block
• Make sure you insert the little slave pin with the flat end facing the trigger pin insertion hole (bigger hole side).

That slave pin on the reinstall is key. Done it with and without and much easier with.

If you got the aluminum FSS trigger, driving the pin while maintaining the bar orientation can be tricky. There is a section in the tray for this, but a vise actually helps more there.

If you decide to switch out the trigger return spring, a dental pick helps with helping sliding it over the slave pin. As the post above, double check your trigger bar orientation before driving the pin.

I think the hardest part is getting the rear sight off for the firing pin plunger.

Sear block should be easy.

+1. A vice can be helpful. I've done two installs and done it both ways...with the block and a vice. The one trigger needed a vice as the trigger pin wasn't properly seated from Apex (they start it for you). It needed the slow, consistent pressure of the vice and I needed an extra hand. But I think that was an anomaly.

The videos are really good. Go slow and you should be fine. And we're always here to help...or laugh at what you did wrong.
