It was a few years ago I reviewed the new Inland M1 Carbine, you can read that article by following this link.  It was a few months ago I got the new Inland Advisor for review. The Advisor is based on Inland’s Paratrooper model and is their rendition of, what was a field expedient, cut down M1 Carbine done by some of the US Military advisors from the Vietnam war. When the M1 Carbine was a bit large to be wielded on some area, such as tunnels, the unofficial M1 Carbine pistol was born.

Initial Impressions  


Left and right sides with the included fifteen round magazine. The M1 Carbine 30 round magazines also worked in the Advisor.

The trigger broke at six pounds with some take up and little over travel. The magazine catch is just forward of the trigger guard, and released the empty magazine dropping it free. The grip is very blocky, and not very ergonomic. Those with large hands may struggle around the rear sling point when gripping.

Rear adjustable peep sight.

The front sight blade is well protected.

The simple conical flash hider worked very well. and is threaded on the barrel with 1/2″ x 28 threads. That being a very popular thread pitch common AR accessories would fit as well as silencers. Be sure to talk to your silencer manufacturer and be sure the can will be OK on a 12″ .30 Carbine, as many silencers that are 1/2″x28 are small caliber pistol calibers. The Liberty Suppressors cans I ran did well.

Though classified as a pistol, the Advisor has the same operating system as the M1 Carbine. The trough in the wood between the sights could be a bit deeper. As it is now, you can see about half of the front sight blade. However, that did not affect getting a sight picture enough to hurt accuracy.

Range Time 


The Advisor is an interesting piece of history, that was never an official US Military issued firearm. Necessity being the mother of invention, the US M1 Carbine was cut down for use in tight spaces and the unofficial M1 Carbine pistol was born. Inland’s interpretation of that pistol is the Advisor and that is about all we have to represent the original M1 Carbine pistol. It would serve as a personal defense pistol, but in my mind the primary reason to have such a pistol is for the fun factor. The Advisor is a lot of fun to shoot and suppressed it is pretty awesome. As mentioned in the video I began to experience some extraction issues at the beginning of the review, so I did send it in to be looked over. I did have it back in about three weeks and the extraction issues were corrected. We ran about 300-350 various rounds through it, with and without a silencer, and there were no more malfunctions. For the review I used the Liberty Suppressors Cosmic, which you can read that review here, and the Sovereign, which you can read that review here. There were a few things, such as the grip, that I did not care for but none were what I would consider a deal breaker. As usual I had several folks shoot the test gun other than myself. Some really liked it and thought it was cool, but a few didn’t really feel the appeal. I can really appreciate it for the history and the fun factor. Being classified as a pistol the Advisor does not fall under the NFA but if you wanted to turn it into a short barreled rifle it can be converted once you get your tax stamp from the BATF. Everything considered it is something that is truly different that has its past rooted in the Vietnam war and place on the pistol range.

I spent much of my youth involved with firearms and felt the call early on to the United States Marine Corps, following in my father's and his brother's footsteps. Just after high school I enlisted and felt most at home on the rifle range, where I qualified expert with several firearms and spent some time as a rifle coach to my fellow Marines. After being honorably discharged I continued teaching firearm safety, rifle and pistol marksmanship, and began teaching metallic cartridge reloading. In the late 1990s I became a life member to the National Rifle Association and worked with the Friends of the NRA. Around that time my father and I became involved with IDPA and competed together up until he passed away. I began reviewing firearms for publications in the mid 2000s and have been fortunate to make many friends in the industry. Continuing to improve my firearms skills and knowledge is a never ending journey in which we should all be committed. I am also credited as weapons master on a few independent films.

  1. I carried a Chopped M2 Carbine (Select Fire version of M1 Carbine) in Nam by choice. I had carried a full size Carbine in Korea, and liked it for it compact size and 15 and 30 round magazine feed system. The only Military type guns I have now, are a 1943 M1 Carbine, and a Inland Advisor, clone to the one I carried in Nam. We had 2 types of “Advisor Carbines” in Nam, the Paratrooper M1A Carbines with the folding part of the stock removed and barrel cut down, and regular M1 or M2 Carbines with the stocks cut down, and barrels cut down. These made Excellent close in fighting weapons.

    My Inland Advisor is fitted in a cut down M1 Carbine stock, like the one I carried in Nam.

    Great little gun.

  2. Thanks for the review. It seems to be a fun gun to shoot. It is not available here in France, only the normal size is (i own several as i just love the M1)

    Before Vietnam The usm1 carbine was also modified like that on the field during WW2, there is several picture of it taken from the western front.

    BTW do you use subsonic ammo with the supressor ? If yes i would love to knwo your receipe.
