You can shoot my M&P9c. Not the same as your Shield, but has the FSS kit in it.
That would be fine. I am leaving the shield as is with the DCAEK and al trigger. It works great. The other changes are for my FS.
Gotcha. We can trade for a while if you want. You can borrow the 9c, and I can see if I can get the AEK in your full size to work?
Do you think I should add the sear first?
Yes. The USB and sear work best as a set. If you want to keep the AEK trigger, you should buy the sear. I had the AEK in one of mine and liked it, but I am now a big fan of the FSS kit. I would recommend buying the FSS kit over just the sear. If you don't mind the difference in price.
Beat me to it SmileDoc but that would be my guess also.Sounds like you need to adjust the loop thingy. Kidding on the term, but otherwise this does sound like the source of the problem.
