The 25 ACP, 32 ACP, 380 ACP and 45 ACP are all creatures of John Browning, they were developed in the first decade of the 20th century (the 25 ACP in 1899)
All these chamberings share a somehow similar pressure profile (between 20.500 for the 32 ACP and 25.000 PSI for the 25 ACP)
They look like increasing scaled up version of each other.
We all know that up to the 380 ACP, the blowback design can perfectly handle these cartridges (the small Walther PPK is the most famous example of a small blowback 380 pistol)
My question is: Would it be possible to build a reasonably sized (let's say a bit smaller and lighter than a 1911) economical blowback 45 ACP pistol??
The round seems low pressure enough that a "regular" slide size blowback system (not something like a Hi-Point) should be able to handle it.
Any thoughts or opinion? Am I missing some technical detail?
Regards
