If it did that, it was probably the effect of a ported barrel, rather than of the handgun design. Barrel porting is done as a recoil reduction measure, and is pretty effective, although it can have some negative consequences in low light firing.
Sounds like you ma have seen a photo of a .45 with a PORTED barrel. An option with many handguns is to machine a couple of holes in the top of the barrel near the muzzle. As the bullet passes those holes on it's trip down the barrel, some of the gas is tapped off, and shoots up through the holes (the ports). The purpose to to help control the tendency of the muzzle to flip up from recoil- but a high speed photo that captures the flash does make it look a bit like a snorting dragon.
Anything you want.
Which make & model??
the .45 Auto CBC is a cartridge for a Semi- Automatic Handgun.
The first auto-loading handgun ever made was the Laumann pistol.
I personally don't think it's a good choice. The .25 ACP has by far the lowest muzzle energy of all the common handgun calibers. Even the .22 short, on average, has much more energy. What that means is, of all the common choices, the .25 has the lowest chance of actually stopping a bad guy if you have to shoot in self defense. If I was choosing a handgun for self defense, I would want something better than (literally) the worst choice.
Nothing.

hello this is a good midrange gun and yes it will shoot semi auto but if you live in the UK then it will only shoot semi auto if it is also bought in the UK it will only shoot semi auto too because that is the law as in other countries it is legal for it to shoot full auto.
