Sgt Preston here. I truely thought & believe that rifled barrels with lands & grooves were technically superior & more accurate than polygonal barrels. Polygonal barrels are cheaper to machine & produce but that's the only advantage that I'm aware of. What do the rest of you have to say. I'm not trying to be a smartass here, but I was suprised by your request. Sgt Preston USMC LLA

Ditto on the above. I doubt anyone would make a less expensive polygonal barrel to replace a factory rifled barrel. Usually it is the other way around.

No one makes them - sorry. Perhaps you might explore higher pressure ammo and stronger recoil springs (if they're safe for your usage) which will give you additional velocity. My younger brother happily uses 124-gr Gold Dot +Ps in his 3913. I've heard of folks using +P+ in their 3913s but I understand this may cause additional wear and recommended that my brother not do so.

A polygonal barrel would only give you an additional 50fps or so, anyway.

Why in God's name would you want a barrel that is less versatile and potentially more dangerous than an ordinary lands and grooves barrel.
Polygonal rifling is not compatible with exposed lead bullets, and it is said that if you use lead bullets with such barrels you can run the pressures up to dangerous levels.
Thus, what is the rush to spend money to replace that excellent S&W barrel? If it is worn out, send the pistol to S&W for a new barrel. S&W makes excellent barrels.
It is claimed there is a slight gain in velocity in polygonal rifled barrels. IF there is any gain in velocity in polygonal rifled barrels, it is so slight as to be not noticeable by the intended target. The veolcity gain with such a barrel MIGHT be the equivalent of taking one step closer to your target.
