The M1 was a redesign to make it simpler to manufacture. They generally
won't take drums, if you are talking about a semi built Thompson, they have
the mag catch lowered and the original mags have to be modified to fit.

I do own a 1928 (AO semi) and I find it beautiful to look at but very heavy to hold. The semis have 16 inch barrels and that does look odd. I have read of complaints about them not being reliable but in part that may be the mag question. Individuals cutting their own holes may result in poor feeding performance of the mags and yet blame it on the gun. I do not understand why AO did not address this by either making the catch in the proper position or making mags for their guns. It would be a fun toy but really nothing else. Too big and too heavy for the caliber. Want to buy mine?

I suggest that if you want a sub gun to play with get an airsoft all metal version and shoot away. I use one of several I own to keep the squirrels off my bird feeder and it is great fun. Cheap, legal, and the better quality AS guns are quite nice. And a lot cheaper.

About a year ago I was visiting a friend and his father brings out one that he'd never shot before. We took it out and..

1.) heavy to hold
2.) not particularly comfortable to hold
3.) broke after a few rounds (lost a spring or something..)

In the early 1980's I got one of the West Hurley 1928 Thompson and it was the worst "jam-o-matic" I ever had. After spending many trips to the range trying to fix the many problems, I finally decided to "start from scratch". I totally stripped the gun down to the bare receiver and barrel. I then bought a complete military parts kit (GI Thompson with receiver and barrel missing.) and installed it in my barreled receiver. My first trip to the range was wonderful. It fired and functioned perfectly and has been doing so ever since. I guess it was all of the newly made Thompson parts which caused the malfunctions but when replaced by GI parts, it made everything right.

Here's a pic of my Kahr/Thompson model 1927A1 that I bought new a couple years ago. It's a beautifully made piece and very reliable. It is also unexpectedly accurate and will group 2-3MOA (off the bench) at 100 yards using the flip up peep sight. Shooting off the bench is really awkward with the vertical foregrip though, so most of the time it's offhand which is way more fun anyway.

Downsides are the long barrel - which doesn't look quite right, weight (especially with a full drum mag), and as others have stated, the need to modify military mags to work. I've got plenty of factory mags so haven't needed to worry about mil mags not fitting.

Another issue for many folks is that for any given application there are other "tools" that will serve better - except for maybe the fun factor. Mine is basically a range toy and it works great for that purpose. I am planning to SBR the thing one of these days just so it will look like a tommy gun should, even if it won't ever shoot like one. That is, I'll SBR it if I ever get done building FALs, so it might be a while before I get around to that...

I really enjoy my Auto Ordinance 1927 as well. The weight of the gun helps keep the recoil to a minimum. You could have the barrel shortened for an SBR. But if you wanted to hang on to the 16" barrel if you want to take it off the registry to sell some day, see if Khar will sell you one their SBR models barrels. That way you have a new barrel with the same finish and aren't stuck trying to reproduce the finish if you used a surplus barrel...just a thought.

Let me play devils advocate for a second. Have you considered a semi auto suomi? They run about half the cost, 9mm is cheaper than .45, the mags are cheap and they work. I bought one as a "poor mans thompson" and have shot the heck out of it. As of now I have run over 1000 rounds through it with no real issues except one of the drums I got. Now in all fairness the trigger pull is stiff, but that aside it fit the bill for cheap blasting and it is pretty accurate.

Here is the link to a range review I did when I got it. Just some food for thought.

Some great advice about the Soumi...now you have me wanting to buy one!
