Convert GSG to other caliber???

[KS1911]

So I was just thinking about this today. I do not know the chamber sizes of the new GSG's, but would it be possible to convert on to run on the 4.6x30 or 5.7x28?

Any thoughts?

I would think the biggest issues, as for any rechambering of a semi-auto firearm, would be

chamber pressures
bolt timing (mass and spring rate)
mag well size
feed path (e.g., magazine, cartridge angle, feed ramps)

...and probably a lot of other issues that I'm forgetting.

Anything can be done with time and money. Lots of time and money.

5.7x28, I think would be too long to fit in the magwell...9mm has a distinct possibility of fitting, but I dont think you could fit something much larger in there...

Here is the info I am finding:

It looks like the GSG Mags have a small wall on both sides, which could possible be opened up for larger round.

You are right that the 9mm may be a possibility. Maybe I should look at something like the makarov for a shorter round.

Thank you for the help.

The GSG is a .22 lr. Converting one to any centerfire would be a huge project and I would still be doubtful of reliability and durability.

The only conversion that would be practical would be 17Mach2

There's no way that the GSG bolt has enough mass to work with the 9mm or 5.7. If it did, it would be a single-shot .22.

If you want a GSG that fires a 9mm; you have just described the parent weapon platform for the GSG - the MP5.

After reading the replies, this seems like a bad idea. I just wanted to through it out there.

Thank you for the responses.
