chiappa makes the 9mm.... they look like a m1... they are not an M1
they have this god awful heavy one piece bolt and oprod....
they jam, they aren't very accurate.
they don't feel like a m1 when firing
the only advantage is that they take 10 round pistol magazines.
this is a video review that is a pretty fair assessment of the chiappa
I own one of these a chiappa m-9 and have several disagreements with this assessment and the video.
First up is the video mentions the action being blow-back - of course they are not going to replicate a real M1 action with a gas piston in 9mm. Suggesting to do so shows a real lack of knowledge of how firearms work. Blow-back is the obvious choice for a pistol caliber carbine. Did they execute it poorly? Perhaps that might be a valid argument, but the issue is the magazine angle in relation to the chamber, not the action.
Second is the video mentions no hold open - I'm guessing they are using an early model as mine and any of the others I've seen in Canada have the same hold open that the original M-1 has.
Third is price - mine was $380 tax in. Not sure where the guys are located in the video, but $500-700 for one is out to lunch.
Accuracy is an issue, but a lot of it has to do with the crapsastic trigger.
Doesn't feel like an M1? Well, they weigh the same, uses a near on dimensionally accurate stock and the 9mm blow-back recoil is slightly less than the .30 carbine gas system of the original.
I think for me the biggest issue for the 'feel' is the trigger sucks compared to my National Postal Meter M-1.
The obvious answer is if you really want an original, get one or a copy that fires .30 carbine.
While I agree with the assessment there can be issues with feeding and quality, these are priced accordingly.
If you are looking for complete reliability in a 9mm carbine, I think it is safe to say you should look elsewhere.
