If yours gets 6-8" out to 25 yards __from a rest__ then yes I'd say get one for sure. There is a major problem with the M&P 9mm's, the compact not as much as a problem.

You could wait until Apex comes out with the new locking block which should fix the dwell time which IS causing accuracy issues with the 9mm's. The older M&P9's are fine though.

Or you could go with the oversized barrels that Grant is getting from Storm Lake. He is the only one getting them since they will be custom fitted to your slide. These are NOT out on the market yet, but hopefully very soon.

Or you could get the gunsmith required ones and also the semi-drop in ones coming out from Apex and Bar-Sto (IIRC they are coming out with 2 options, won't be for another 2-4 months though). I'd do research on both, have to use your Goog search Fu as my post on this subject was deleted last night to where you can actually find the info.
