Converting M&P FSS trigger back to stock

I have purchased my third M&P (Pro 5", compact and now a FS) and the previous owner installed a FSS trigger and does not have the original trigger components.

This will serve as my carry and as as a backup USPSA production pistol. I'm not sure if I will like the FSS trigger for a carry gun and it certainly isn't production legal.

I'm going to leave the FSS on for a while and get a feel for it, but in the event I want or need (for USPSA or carry) to switch it back to a factory style trigger I'd like to know what I need.

What is the best way to convert a FSS trigger to a standard trigger? I have the Apex CAEK kit in my 5" and the rest of the trigger components that I took out of that pistol.

Thanks in advance.

If you are you going to use the parts from the 5" you'll need at the least this...

M&P 9/40/357 Trigger Bar Assembly [1688] - $12.99 : Welcome to Speed Shooter Specialties

If you didn't have the others parts you would need the following.

Thank you Jason. For some reason I thought there would be more to it than that.

On an unrelated note, that is a fantastic collection of quotes.

I think I got it all correct. I do not have the FSS so I'm not 100% sure if the FSS kit changes out the striker block spring or not. I'm sure someone will chime in if that is the case.

Aren't those quotes a kicker, I have so many more great ones squirreled away.

I believe the FSS kit still comes with all the DCAEK kit's springs, as long as the original owner installed the whole kit and didn't swap springs out.

Jason has done a thorough job of listing all the parts you would need to get it back to factory (once he including the striker block spring). You may need to tweak the trigger bar's engagment loop a little bit to get the timing back to factory. You're welcome to come back here again if you need help with that.

One thing to consider: If you would like to restore an FSS trigger to a DCAEK trigger all you'll need is a factory trigger bar and an APEX Hard Sear... possibly the regular USB (although the FSS USB works fine too). Same caveat as before about the original owner swapping out springs.

Awesome, it sounds like swapping the trigger out won't be terribly difficult. I don't need it to be stock, just USPSA legal.

I just picked it up and I gotta say I'm digging the FSS trigger. I may still swap out the factory trigger for large matches where it will serve as a backup in case something breaks on my 5"

Join the club.

If you need one that's USPSA production legal, you could probably trade with someone in the forum who has a factory trigger (or even an APEX DCAEK trigger ) that actually wants your FSS trigger. You might even score a Benjamin and a couple/few other dead preidents in the trade.
