I just finished swapping an Apex Tactical flat trigger for the stock one in my Walther PPQ M1. What a difference! The pre-travel is greatly reduced, which was my only gripe about the PPQ. I'll post a range report after I (eventually) make it to the range. 

Will this trigger also work on the M2 version?

Where did you get it and how much is it?

Search for a thread on this. There is a spring to change to reduce the trigger pull to about 3.5 pounds if you're looking to do that.

Found it.

 

I didn't read that linked thread but the Duty-Carry AEK trigger return spring is stiffer than stock, at least with the M&P. Just using the stock return spring will give you a lighter trigger.

 

However it may be so light that the trigger safety doesn't deactivate very well so you'll have to play around with that.

 

If you got a competition AEK then this is all moot.

Then you should, if interested. I got the spring from McMaster-Carr. @Howard
