I have an MP40. Out of the box, the trigger was VERY "crunchy" or "gritty" from start to break. After cleaning and lubing, the grittiness was reduced (to a shorter section of the overall travel), but not completely. Running 100 rounds through it after that did not seem to make any improvements. I feel I was very careful about where I applied lube to the trigger mechanism.
Example of trigger pull (hope this makes sense):
>--smooth--gritty|stop--pull harder--break)
Each of these "phases" of the trigger is pretty small but that "crunchy/gritty" stutter right before the point where I have to apply more pressure to actually fire the trigger is quite noticeable. The travel up front, before the gritty section is smooth and light.
My question(s): Is this just the way a stock MP trigger is? Should I send it back to S&W, or is this normal OOTB and maybe it just needs a trip to Dan for a trigger job? Or is this normal and a few more hundred rounds through it will smooth it out automatically? If it wasn't for the gritty section, I would be happy with the overall trigger feel.
