Storm Lake or KKR?

[m4brian]

What is the best drop in barrel for the M&P?

Easiest to get fitted? Accuracy? Dealers? Etc.

Thanks.

I'm going with Storm Lake, as it looks to be plenty accurate.

EDIT: You said drop in. Grant is fitting the Storm Lake barrels. I'm not familiar with KKR, I have heard that KKM is a good drop in.

Storm Lake makes great drop in barrels, but with the M&P you would be better off having it fitted.

I have a KKM, and it performs very nicely. I have zero knowledge of the Storm Lake, but have heard that they are better when fitted. I went with the KKM as the reputation, as purely a drop in was very good, and it has not disappointed.

Had really good results with the KKM barrel. Received it about a week after I ordered it. First shot centerpunched the bullseye at 25M.
