Ever re-installed the same parts in error?
I bought the Apex hard sear and the USB to improve the trigger on my M&P compact. Somehow in the process, I managed to take out the sear and put the same sear back in. Maybe that phone call in the middle of things had something to do with it.
Anyway, I wasn't so impressed by the upgrade and started wondering if I screwed up. Googling images of the sear today, clued me in, I had put the OEM part back in.
Let me tell you, the second time you do this with a manual safety M&P it is a lot quicker.
The trigger is now a lot better.
I really hate brain farts.
