The 27a1 is straight blowback with a bolt having marginal mass for the job. Bolt velocity with standard ammo is pushing it as is. That said, will +p “blow up” the gun? Not likely. If the use is limited as Frank has indicated he should be ok, but a steady diet of +p would not be advisable for the 27a1 IMO.

( kinda like a mac 10 ) and the gun stopped. I thought it must have jammed, but I found the magazine was completely empty and I was now being showered by falling brass. Later in the week while I was talking with Stan Andrewski on the telephone, I shared my range experience with him. I asked if that Remington .45 + P ammo would accelerate the RMP's my Thompson exhibited and his response was " Sure it could and it'll crack the back of your receiver if you keep using that ammo " Based on that sound advise, I only use factory practice type
( Federal red box, etc., etc. ) in all of my Thompsons.

Overpowered ammo in a self defese situation would be ok. More than likely you will never have to defend youself, but if you did and you cracked a Kahr or WH Semi, you wouldn't be out all that much money anyway.
I would be willing to destroy my own 28 Savage if I had to crack the receiver to save our lives. But the military used ball ammo, and thats what I use. It worked for them.
Shooting a perp with a one second burst from a Thompson delivers 2300 grains of lead and a whopping 3500-3800 foot pounds of energy. I believe these numbers beat a shot gun blast, but most folks dont sleep with their thompson (I have once or twice). Shotguns are easy to get for under 200 bucks. The damn transfer tax on a Thompson costs that, so thats why I say "Use a shotgun for home defense. "
Here is some interesting reading about the 45 Acp I found.
