Can anyone tell me if having the trigger kit put in my M&P 45 would void my lifetime warranty? Would it be alright if it were done by a S&W trained tech and was the S&W kit?
Thanks in advance, Best, Frank.

Just put the factory parts back in if you need warranty work done.

Thanks, that makes sense. As long as I do not alter anything on the frame or original parts, I am good.
Best, Frank.
