Why no muzzel rise on these ISPC shooters
 
I spotted this video and noticed that there is no muzzel rise from recoil.

What is the deal here? I'm sure that my pistol would not even compete with these guys so what the difference?


Thanks

a lot of them use underpowered rounds

While it may appear that there is no muzzle flip/rise in that video, there is. The muzzle rise is minimized by several factors. Just a few of those factors are:

1. Specialized equipment - like the compensator fitted to the barrel of his pistol.
2. Shooting a fast (not light) load that shortens the recoil time allowing fast follow up shots.
3. Good shooting technique.
4. Practice. Shooting a hundred thousand rounds (or more) every year.

I place the strongest emphasis on the considerable amount of time spent practicing. I know shooters who can shoot an uncompensated .45 ACP 1911 A1 with little or no perceptible muzzle rise/flip using "heavy" loads (not light loads) almost as fast as the shooter in the video (almost). A very good shooter can make shooting well look very easy, but it's not. It takes an insane amount of range time to become that accomplished.

About $10K of tooling and engineering. Pretty much the same reason one neighbour's 'Vette takes the corner at the bottom of the street at 70mph daily, and the other neighbour's Civic wound up on it's roof at 40.

That gun was designed to bust paper targets, not to kill people, nor to work well when dirty. Yours will. His grips are likely custom, costing more than your entire gun. But you can be sure he's not relying on it as his daily carry piece.

The weapons are compensated. The muzzle extends into an expansion chamber that vents gas upwards as the bullet leaves the barrel. This upwards gas jet pushes the barrel downward at the moment the bullet leaves the barrel.

Wrists of steel help some, too.

Compensator at end of barrel is the big deal.
I think that many of the fast guys race with a .38 super cartridge, which has a bit less recoil than a .45

Jeff Cooper, who was the founder/first president of IPSC, used to, in his Gunsite Gossip/Commentaries, bemoan what the International Practical Shooting Federation competitions had become, noting that the pistols were hardly "practical" anymore, what with the huge muzzle brakes/compensators, the gigantic magazine wells, and the big optical sites attached on top.

The USPSA Production and Limited Divisions still use plain old production guns, and the most they let you change are grips, sights, slide stops, etc., but no big optical sights or compensators or porting or any of that stuff is allowed. Seems a bit more "Practical" than the open race guns.

Exactly. It's mostly practice, practice, practice.
