It is a thing that you screw onto teh end of the barrel to prevent the gas escaping out the muzzle but forcing the gas into the gas chamber which recocks the weapon.

The difference between a blank and a live round is that a live round is a plug in the barrel until it leaves the muzzle so the gas can enter the gas chamber and recock the weapon before the bullet has left the muzzle.

With a blank there is no blockage so all the gas escapes out the muzzle so the weapon does not recock.

However saying that I was not aware that semi automatic pistols required a BFA considering how short they were, but I stand to be corrected. I have fired the Sig Sauer but only with live ammunition. We used blanks in our 9mm Brownings and I never saw anyone fit a BFA to them. They don't fit in the holster with a BFA attached anyway.

HTH
Still not sure why I put BFR rather than BFA, not even like the keys are that close together

Again, vague recollections with the Browning, thought they had a blank firing barrel - smaller bore to restrict the gas flow and force it to re-****. May be wrong (again)

JUST KIDDIING!
If that's the case she'd be more likely to beat you to death with than shoot you anyway

I have shot the browning hi power with live rounds never blanks samew with a Beretta 92F. I am not asure exacxtly how they would peerform with blanks but i would not thought they would recock themsleves.

I am pretty sure the ones used in films have restrictions in the barrels, you can see them on M16's and .50 cal brownings easily.
I would imagine the force required to **** a 9mm semi is quite a lot less than your average 5.56m rifle.

I have an 8mm blank firer 92F at home that has the barrel blocked off (in the middle so it still looks like a barrel at the business end). Not to sure how the cycling works but it fires 17rds no bother as fast as I can pull the trigger. Still going strong. Not bad for £70.

I also recall the BFA's were also meant to dispurse some of the crap that comes out of the blank to the side to avoid injury to anyone your firing at? Or did I just imagine that?

Juding by the rather graphic demo we used to give the new recruits on how dangerous an SA80 was, even with BFA, I'd say maybe, but not much. We were told not to fire at anybody within 20m (100m for civillians). I suspect you'd be safe in 10m, maybe less, but you wouldn't want to get hit from a few feet, that's for sure.

In cadets we used to do the old shoot a 4 pint milk carton at about 5 ft for that demo

Modern rifles tend work in a different way. They have ports that take some of the gas away from the combustion chamber and channel it into a piston/cylinder arrangement that operates the action. Newer semi automatic shotguns work on the same principle. The reason for this is that the older designs relied on the recoil, so if you were using lighter loads then you'd often get jams.

I have an 8mm blank firer 92F at home that has the barrel blocked off (in the middle so it still looks like a barrel at the business end). Not to sure how the cycling works but it fires 17rds no bother as fast as I can pull the trigger. Still going strong. Not bad for £70.
The loading mechanism in those replicas works in exactly the same way as the real thing, except that instead of the bullet blocking the barrel temporarily you have a permanently blocked barrel with an exhaust port in the side of the breech to allow the excess gas to escape.
