Until you can answer the question of velocity loss caused by the cylinder gap and account for it in the analysis in a meaningful way for the given revolvers involved, your logic and results will continued to be flawed.

I doubt anyone here has standard industry test bbl’s for comparison so until that information is possible any revolver vs. semi-auto comparison that uses a revolver bbl with a greater rifled bbl length ~0.25-5” over that of the semi-auto rifled bbl length will be extremely flawed -- in this case by ~1.24".

The simple velocity numbers gathered by various known bbl lengths and posted in this thread supports the accounting of this issue. Regardless of what you believe until those key issues have been addressed appropriately in the analysis it doesn’t matter what you believe because the data overwhelmingly supports that my analysis is correct.

This should settle it. Steve did Chrono the 357mag and 357sig. 357sig wins hands down, even with the chamber being counted as the barrel length in the Glock 32.

Data sources:
357mag
357sig

Now I'll use 125gr and 4" barrels for both calibers:

357vs357.xls

357sig is the clear winner, and remember that's counting the chamber as part of the barrel length in the Glock. The Glock 32 barrel is really 2.86 inches; the Colt Trooper is a true 4.00 inches.

1347fps vs 1271fps - 357sig ownes 357mag.
