I can't get the takedown lever off of my M&P9 (something is up with the spring or something) plus I have an Apex Polymer trigger kit to install and threaded barrel that will need some light work to fit.

Anyone got any recs?

Edit: Managed to solve the takedown lever issue myself. You'd think there would be way more information available about such a long running line of pistols but there isn't a lot. Thanks for the recs on the trigger and barrel fitting y'all!
