Why is semi-auto so dominant in ISSF 25m centerfire shooting event?

Title says it all. According to ISSF rules, revolvers are allowed, but almost every shooter uses semi autos like pardini in .32 cal. Has anybody seen competitors with revolvers instead of semi-autos in ISSF 25m centerfire event?

That's a gun you will not see robbing a Convenience store, right? Try tucking one of those into your pants.

I think because autos are used in the .22 events and common handling is a benefit.
Even common actions, some can be had with interchangeable .22 and .32 uppers.

You will not see any firearm robbing a convenience store.
Very few revolvers are made that shoot .32 S&W Long accurately enough. However, you don't have to move any part of your body to cock a pistol. Means there's no risk, of any kind, of you changing your grip.
Spelling and grammar count!

Semiauto triggers are better for accuracy. Semiauto barrels are more accurate than revolver barrels; one chamber aligns the same to the rifling whereas six will each be different.

Same thing happened in the late 50's and early 60's with NRA bullseye pistol events when top 'smiths learned how to make M1911 pistols shoot more accurate than any centerfire revolver.

Regarding guns and crime......

Guns do not commit crimes. People do.

If guns commit crimes, how come they are not tried in courts?

There are no laws stating it is illegal for a firearm to commit any crime.

Revolvers have been out of fashion for competitive events for years.

Before I went to a 3 calibre Italian pistol, wooden grips your hand fit inside of.
I shot a .22 S&W Model 52, and an S&W in .38 Special pistol, shot wadcutters, .148g rimmed cartridges. Had to be careful how you fit them into the magazine
rims had to face the front!

I've shot both my Dan Wesson .357 with wadcutters in the centerfire stage and a S&W 25-2 in the 45 stage in local league matches just for the experience. The single-action triggers were just fine, both having been worked on.

It takes some work, but I've got a revolver that shoots up to my best 1911, running under an inch at 50 yards (a Ruger Redhawk) and I 've seen others. Good revolversmiths who can make that happen are vanishingly rare.

The main problem with revolvers up against pistols is it simply takes longer to cock the hammer and get back on target with one hand than it does waiting for a pistol to settle. You feel rushed, so it's just not as easy to keep pace without hurrying shots. Old timers claimed cocking the hammer actually helped them get back on target. I didn't give it enough chance to acquire the feeling that was happening. I suspect most people don't, and that's resulted in fewer good revolver shots and that, in turn, is one reason there are separate revolver matches today.

Jeff Cooper suggested a variation of the Weaver hold in which the weak hand thumb handles cocking the hammer. But while I think that could work on a bull's-eye target, the rules would not allow the spare hand's involvement.

The fact is, semi-auto mechanisms get you back on a target with greater speed and less physical effort than manual actions do in handguns, rifles, and shotguns unless you are willing to undergo some very lengthy and dedicated muscle training. (And even then, the greater muscle effort is still with you.) It's why the Garand was an advantage over the Mauser. Less time back on target means more time to place shots. Reliability and complexity matters aside, self-loading is a technical advancement.

Another advantage is that you can load all your mags the night before and then concentrate only on shooting during the match. It's not a big advantage, but it's one less thing to mess with at a time when avoiding distractions is helpful.

Also, all else being equal, felt recoil tends to be less with a semi-auto. Again, maybe not a huge advantage, but it makes shooting a little easier and every little bit helps.

Finally, shooting semi-autos tends to just be less messy than shooting revolvers. Cleanup for you and for the gun is easier and while that may not buy you anything during a match, it can be a consideration when making the choice. I tend to shoot my semi-autos more often than my revolvers for this reason even though I really prefer revolvers.
Do you know about the TEXAS State Rifle Association?

I don't know squat about handgun competition but I have a feeling that every gun, regardless of action type is worked over for serious competitor's. Year's ago in Colorado in a gun store I saw a DA revolver worked over as a competition gun by the gunsmith Clark, in California. The hammer was bobbed off and in the trigger guard was a rubber bumper behind the trigger. You pulled the trigger and the bumper stopped it and the trigger release rivaled most any fine tuned rifle I've ever seen. No serious competition is anything used as issued factory equipment I don't think except in bowling!
