Drop in 357 barrel for M&P 40

[bripro]

I was lucky enough to score a 357 sig barrel for my Glock 27 for free and I have fallen in love with the round. I have been looking at barrels for my M&P 40 full size. I have found S&W barrels for around 80 bucks (out of stock though) and Storm Lakes for about 150. Does anyone have either one. The Storm Lake claims to give more accuracy by offering tighter tolerances but this would be for carry and I am afraid the tighter tolerance could mean less reliability. Any feedback is appreciated.

It is unlikely there will be a reliability issue due to the tighter tolerances. They are in thousandths of an inch and the increase in accuracy will not be mind warping, though noticeable, maybe. Big price difference. .357 Sig is an impressive round, but if you hand load, or buy from the right manufacturer, you can get similar performance from a .40 S&W, with a touch more knock down power.
