I am 99% sure that it is a 1-30. And as the reason given above it is a proven twist capable of shooting 90% of the bullets on the market today very accuratetly. The obvious exceptions are the longest non--lead copper bullets, the newer very long .357 bullets, and long full bore lead conicals.

I believe/think when the math guys did the calculations for 45 twist, using the commonly available bullets it computed to be 1-32 as the idea rate, so Knight has made it a bit faster.

But for some the 1-20 would be great twist.
