I’m asking about a hard grip as if someone were trying to wrest the gun away from the shooter and one or two shots were fired?

I am curious what the effect would be on operation and cycling of the gun. If there was no interference with the slide, would it still function properly?

(And what I’m not referring to is holding onto it long enough for it to get uncomfortably hot. I know that.)

On a pistol with a fixed barrel, such as a P7 or a Walther PP-series pistol, probably nothing, but on pistols which have a conventional locking system, it would be one shot (if even that) and done.

Yes, thanks for clarifying.
I was thinking of pistols whose barrels move during the process, not fixed barrels.

Para has the answer in principle. But in fact the answer probably depends on the direction of the forces involved in "wresting". If you pull likely you get a single shot. But if you push as you might in a wrestling match you likely will get a cycle as that is the actual goal of the booster. And some guns and certain ammo just don't care (meaning that they should need a booster but run anyway).

I have done it. You get one shot and a failure to extract. At least, that’s what I recall. It was some time ago.

Thanks for the responses, and especially for the voice of experience.

I haven't held the can, but I've held the slide, in an effort to eliminate the slide's movement, for a quieter suppressed shot. Turns out it's VERY difficult to prevent the slide's movement. Even with one man holding the gun, and another grasping the slide as tight as he can, it still moved a smidge out of battery.

What caliber was this? I've held the slide forward on a Glock 19 with my firing hand thumb with no problem.

226 MK25 with an AAC Tirant-9, shooting 147gr subs.
Perhaps the booster encouraging the unlocking makes it harder to hold? That's the only thing I can think of. On that pistol, on that day, I sure didn't want to put my thumb behind that sucker.
