OK, you posted a bunch of pictures. Thanks. But what does that prove??? The barrels are obviously supporting the 40k psi 10mm cartridge? Why can't they handle the 40k psi 460 rowland???

So, I will ask the question you failed to answer.

If there is NOT enough chamber wall thickness, how is Johnny Rowland safetly selling these kits for Glocks and Springfields...and even 1911s for that matter?? I would think that the barrels would be of the same construction and thickness, given they are drop-in installations????

Since you know so much more about this than me, please answer the question.

Thanks!
