40 cal barrel

[tk4]

Is there a 40 cal replacement barrel that would give accuracy comparable to the Apex 9mm semi drop in barrel?

Anybody using a M&P 40 in Limited, and using a barrel other than factory they are happy with?

I have KKM barrels in .40 and 357sig , do not know how they compare to other brands but they did improve accuracy over the stock barrel 40 barrel.

Agreed, the KKM .357 Sig barrel I bought (5.5" threaded) is tack accurate in my .40 caliber 2.0. I have not done anything to the trigger so I suspect KKM is a better frame / slide fit?

every kkm I have bought has improved accuracy for sure, they do nice barrels

The 357sig barrel is the most accurate set up I have for a M&P.  

 

I would put more time into the round if there was more industry support behind it. 

 

I have a 40 to 9 Apex barrel shoots well , have considered cutting it for a 357sig chamber.

It's  a shame too... even Sig bailed out on the cartridge. It may be a bit of a PITA to get it sorted out on what bullets it likes and paying a bit more attention to load than a 9, 40 or .45 but once it's all sussed out the results are well worth it.
