Several years ago I bought an M&P 45c because I thought it could serve dual purpose as a carry gun and range gun. Naive to the consequences discussed in this thread, I had the Apex trigger kit put on it to improve my accuracy when shooting compettively with it at the range. After I became aware of the legal implications of messing with the trigger of a carry gun, I ended up selling it because I was afraid to carry it.
I ended up buying a Springfiled Range Officer 1911 for range use.
