Opening back up and avoiding duplication of efforts
Today I seen some high quality photos of the Chiappa M1-9 psoted by the Canadian importer and I had a thought, which I will get to in a moment.
During my search for a Non-Restricted M1 Carbine, these rifles popped up as an option, I had dismissed them based on the magazine selection and apparent recycling of components from their M1-22 offering. Good enough for a .22LR yes, but not in my opinion good enough for a 9mm. I kept looking and gave this a pass.
Back to that thought...
Seeing the photos of the top of this gun made me ask, "what is that monstrosity on the slide!?"
This:

I thought about it for a moment and realized that this gun is almost certainly straight blow-back and that cast anvil of a block of metal is to provide mass to slow the action cycling. This gun appears to be nothing more than an upsize of the M1-22 which does not have a gas system, and as such is only a visual copy of the real M1 Carbine.
While blowback is ideal for a light recoiling .22, and other dedicated firearms I personally think that using blowback in this example, which attempts replicate a gas operated gun, is being cheap and lazy.
