I was surprised how smooth operating M1-9 was. It operated flawlessly for me with the initial 150 rounds. Still will need to do more testing with different brands of ammo but so far so good. Although it is touted as a range toy, plinker, it could be pressed into a nice little truck gun, PCC role. I used after market 18 round Beretta 92 magazines with it and they ran just fine and was accurate for what it was intended to be a PDW/PCC. My only quip is the rear sight which is easy to adjust for windage and elevation, but the ghost ring rear site aperture which can be manipulated on a incline with detents for elevation adjustment, if you not careful, can be easily pulled off of the rear site, and you can lose the small detent spring. It's almost impossible to find and replace, but the saving grace is when I called Chiappa customer service, they sent a replacement rear sight out at no charge immediately-no hesitation and no fuss. The helpful customer service representative said that those detent springs were so hard to install that they just sent a whole new sight apparatus instead. It would be less authentic looking but I think a little stop at the rear of the sight would be helpful, but at least the customer service is solid. Enjoy the firearm and its a lot cheaper to shoot than .30 Carbine which now costs "an arm and a leg."

I am very happy with my purchase, the rifle works perfectly and I had no problems. The only issue was that it came with 10-round capacity magazines (which I solved by removing the stud inside the magazine that prevents increasing capacity, now each one holds 16 rounds). Another thing I noticed is that it shoots a bit low (which I also resolved by filing down the front sight). The carbine is a great option; instead of buying a real one, you can have the same carbine that fires 9mm, which is cheaper. Chiappa could have done a better job on the design by creating magazines that looked the same as real 30 cal magazines; that is my only negative review.

This is a great carbine for the price. It looks fantastic, shoots exceptionally well, and has no issues with accuracy. I would definitely recommend it.

Feels like original m1 carbine. Fired flawlesly.

I wanted one of these for awhile, and all I could find was the model with the plastic stock. Ugh! I got on Bud's waiting list and got this wood stock version and I am very happy with it. Uses easy to find Beretta 92 mags! It took about 100 rounds to break in using 147 grain rounds, and now it is totally reliable and a lot of fun. Highly recommended and fun rifle! Bud's is the place to find them!

I have several Chiappa weapons and this 9mm carbine was of the same high standard.

I love this M1 carbine in .9mm cheaper to shoot than the real thing. Buds is awesome

I’ve always wanted an M1 carbine every since I was a little kid. Now, you either have to pay exorbitant prices for a 30 caliber version, which is very expensive to play with or you can buy the 9 mm rough production like I did. As long as you buy decent ammunition, you can shoot this thing as fast as you want to. It’s pretty accurate and a blast to fire! I highly a recommend it. By the way, lots of accessories are available for this on eBay I’ve already got the sling, the pouch, the oiler and the bayonet.

This little M-1, 9 carbine is fun to shoot, and 9mm is affordable. Ran 100 rounds of Blazer brass through it and had no issue at all. Some of the video's show folks shooting cheap ammo, and that's not the guns fault for not cycling. The only negative I have, is the plastic parts, but hey, they keep the price down that way. Thanks Buds.

A missed opportunity. Would NOT recommend but personally still enjoying it.
Shot 300 rounds of CCI Blazer 147grains.
0 feeding malfunctions.
Rear sight came loose
Front sight came loose
On one hand its a M1 Carbine replica in cheap 9x19 ammo.
On the other hand its a low quality, badly designed range toy.
If you like changing spark-plugs, tuning carburetors, working on watches or fixing old school electronics, you might be able to put-up with some of the silliness of this rifle's designs.
Good:
Looks good.
Quality magazines, 2 included
Accurate (see cons)
Fun to shoot
Cheaper than real M1 Carbine
Lighter than Ruger PC Carbine
Cheap ammo that is interchangeable with my other guns, and I don't have a specific, one gun caliber to buy. This is probably the biggest "Good" for this rifle.
Bad:
Plastic parts (annoying)
Included magazines hold only 10 rounds..
Have to be creative to clean it. Since there is no bolt hold open feature I saw two options.
1. If I remove action from the stock, reinstall the magazine catch and pop in magazine, it can hold the bolt back. Works but obtrusive, hard to clean the bolt face with the magazine in there.
2. Use a hand clamp from Walmart and clamp the charging handle to the back of the receiver to hold the bolt open. Works like a charm, but absolutely ridiculous to even be doing something like this to clean a gun.
Bolt is held on the empty magazine by the magazine's plastic follower. Removing the magazine, slams the bolt forward and it catches the follower, scratching the top. I don't know how long the plastic will hold until there is a sizable groove that might start affect the feeding.
Front sight is held by a roll pin. Roll pin is working itself loose and the front sight is wiggling now, after 300 rounds. Will use this opportunity and pull it out, to take off the front sight.
Will file the front post to make it a bit more narrow for a bit more precise shooting.
Will cut off the plastic bayonet lug, might even replace the front retention ring with a metal one from M1.
Rear sight completely came loose at 150 - 200 rounds mark. It has a tiny retention screw, that came undone and allowed sight to wobble in its dovetail groove.
I used locktite on the retention screw, it held through the rest of 100-150 rounds. Don't know how much longer it will hold.
The rear aperture is adjusted for the elevation on a ramp with a detent holes set at certain intervals. The detent spring is very weak, and the aperture did not hold its position at the highest mark. Would slide down to the next detent hole after the first shot from the recoil. I had to disassemble the rear sight and stretch out the detent spring a bit to make it press a bit harder. Will see if that helped, but it does click a lot more positively into those detent holes. It was a B*TCH to get that tiny detent ball back, and there are TWO of them on that rear sight.
Wood dents and scratches EXTREMELY easily. Had a bit of scratch in the finish from the factory already.
Conclusion:
If you want a 9mm carbine, get a Ruger PC 9.
If you want a M1 Carbine, get an M1 Carbine.
If you absolutely want the look of M1 Carbine, but want to save up on ammo, and willing to put up with and work through the quirks of this rifle this might be something to look at. If the rifle holds up well, it will be worth it in a few thousands of rounds. If it keeps coming loose and undone, then no. 30 carbine caliber is not THAT much more expensive.
