I found this post I made 12 years ago. Thought I'd repost it for informational purposes.

Its raining here today so I got out my Craftsman thread pitch gage and my Frankford Arsenal digital calipers and decided to do some measuring of the large and supermag barrels. I'll post my results below. All measurements made at frame end of barrel.

CALIBER Thread Diameter Pitch

357SM .657 32TPI .357

375SM .686 32TPI .371

41Mag .656 40TPI .417

414SM .656 40TPI .417

44Mag .686 40TPI .426

445SM .686 40TPI .426

45Colt .688 36TPI .450

Anything worth doing is worth doing well.

If a man designed it, and a man built it, then a man can fix it.
