thompson semi auto
i have a 1927 a 1
semi auto it has a closed bolt system

Open bolts were outlawed by the Alphabet Boys some years back. I think if they were made before that date they were ok but any after whatever date it was is/was a no-no.

the a1 was made in 74 i guess the older model could be changed out with a kit from colt

Here's a picture of my Commando...

I got six 30 round sticks and a 50 round drum...and it spits 45's as fast as I can pull the trigger...

I would liked to have the shorter barrel, but I'm not willing to pay the tax and invite BATF into my house....

What kind of a group can you get out of that rifle at, let's say, 50 yards? The sights on the one I looked at were a little more crude than I had expected. Right now I have a Bushmaster Carbon 15 in 9mm that scratches my itch for a rifle in pistol chambering (and a Marlin 1894C), but sometimes those rashes spread and you have to get something else!!!!!!

I get very good groups from my Tommy gun out at 50 yards with the 16 1/2" compensated barrel.

Having said is a pistol round ( .45acp )...and anything past 50 yards calls for a rifle round like the 30.06...

But up close...used as a trench broom, as it's inventor envisioned...the word devastating comes to mind
