GregInAtl Posted May 23, 2018 Share Posted May 23, 2018 I was going to order the Apex Competition Action Enhancement Kit (AEK) for my newly purchased M&P CORE 9mm w/5" barrel. Apex also offers the Forward Sear and Trigger Kit. Does anyone know which would improve the M&P trigger the most. They are mutually exclusive, according to Apex Link to comment Share on other sites More sharing options...
Bkreutz Posted May 23, 2018 Share Posted May 23, 2018 FSS and Trigger kit is much better than the AEK, the only choice is curved or flat trigger (I prefer the flat). Link to comment Share on other sites More sharing options...
Avedis Posted May 24, 2018 Share Posted May 24, 2018 The CAEK are a solid upgrade in that they remove almost all most of the grit in the trigger pull and clean up the break. The CAEK will have little affect on the pretravel, and you'd have to purchase an additional part (Action Enhancement Trigger body) to get rid of the factory hinged trigger design. To answer your question, which will improve it the most, the FSS is a pretty clear cut choice. It will do all the same things as the CAEK in that it will smooth/crisp the trigger up AND it will reduce almost all of the pretravel. Flat and curved are both great, they have the same internals. Apex is correct (of course), they are mutually exclusive. People were installing CAEK, DCAEK, AEK kits then months later trying to add the forward set sear trigger bodies to the kit. The issue is the FSS trigger bodies have different geometry, and wont work with the sear included in the AEK kits. It became such an issue that Apex had to stop selling the FSS trigger bodies as a stand alone product. https://www.twobrostactical.com/collections/m-p/products/m-p-forward-set-sear-flat-faced-trigger-kit-aluminum https://www.twobrostactical.com/collections/m-p/products/m-p-trigger-forward-set-sear-polymer-trigger-kit Link to comment Share on other sites More sharing options...
mciver52 Posted June 5, 2018 Share Posted June 5, 2018 Run that FSS and try leaving the original trigger return spring in...that has always given me the lightest trigger pull. Link to comment Share on other sites More sharing options...
stick Posted June 5, 2018 Share Posted June 5, 2018 I run the FSS with flat trigger in my M&P pro. I also use the competition springs. My trigger pull is about 2lbs. Link to comment Share on other sites More sharing options...
fxdc Posted June 6, 2018 Share Posted June 6, 2018 I have the same as stick.... Got 1lb 12oz, after 1k am getting 1lb 9oz . If I polish my trigger bar I may get it lower. Link to comment Share on other sites More sharing options...
jpm2953 Posted August 23, 2018 Share Posted August 23, 2018 I was getting just under 2lb trigger with my FSS kit. Link to comment Share on other sites More sharing options...
biggulp Posted August 24, 2018 Share Posted August 24, 2018 If it's for gaming or a range toy, the FSS is the way to go. Link to comment Share on other sites More sharing options...
HBurgSTi Posted September 23, 2018 Share Posted September 23, 2018 I know it kind of a late response, but... If you are going to shoot carry optic you can't modify the external trigger; thats why i just used the AEK and reset assist... Link to comment Share on other sites More sharing options...
Bkreutz Posted September 23, 2018 Share Posted September 23, 2018 External trigger modifications are allowed in carry optics (new rule just enacted this year) You can find the latest rules at USPSA.org Link to comment Share on other sites More sharing options...
HBurgSTi Posted September 23, 2018 Share Posted September 23, 2018 oh, sorry... I haven't looked at the CO rules in a while; I moved to limited because I personally shoot irons better than a dot... Link to comment Share on other sites More sharing options...
