I would appreciate some advice about getting my M&P tuned up. I know S&W offers a service, but I want to know if there are any other gunsmiths out there that do similar work. Again, any information will be greatly appreciated.
As long as it shoots good, there is no need for this stuff. Trigger works and ramp jobs constitute "custom work" and may void your warranty. If you are having feed problems, I would suggest trying a few different types of ammo and if it still isn't working correctly, send it in for the free warranty coverage! It is there for you to use it before your warranty time is up, so take advantage of it while ya can

I had S&W do the M&P Action Package done on my M&P9FS - made a MAJOR difference in the performance of the gun. Trigger is MUCH smoother - not quite 1911-like, but close. I recommend getting this done to any M&P.
