Is there a 9X21 conversion available for a Glock34?

I dont know about a complete conversion kit (or if you need one), but here is a barrel that it sounds like it would work.  Click me

I'm not sure if your standard mags can be used or not, the 9x21 is only 2mm longer in the case.

9x21 will work on the 9mm frame and 9x23 needs the 45 frame.

9X21 was an attempt by IPSC shooters to make major caliber in smaller framed high cap guns.

In the 1911 wide body type guns they were loaded a bit longer so lower pressure.
In the smaller framed guns like the EAA Witness and Springfield P9s they had to be loaded to the same overall length as the 9mm so I doubt the pressure is any less.

Anyway I have the Witness Silver Team in 9X21  now that IPSC has lowered the Power Factor to the point that 9X19 can be loaded to major it can be shot a lot cheaper than 38stupid or 9X21 since 9mmX17 brass is so cheap.

But anyway you are probably trying to shoot in Limited class rather than open and trying to cheat the gun into Major. A std. barrel could just be reamed 2mm deeper, but I think it might be best to go with a competition barrel more supported chamber than a factory Glock since you will have to load them short to fit in the magazines.

Brass is drying up since no one shoots it anymore. The commercial loaders for IPSC don't load it anymore.

If you want a longer barrel here is a source.

I really like the 34 because it shoots great and the ammo is affordable.  I was considering changing it over to a 9x21 to make major but it is appearing rather involved.   I don't particularly want to do any complicated reloading.  Would I be better off just getting a Glock 35 (.40) when I'm good enough for it to make a difference?

When you are good enough it will make a difference then it will make no difference at all because 9mm minor power factor scores the same as 40 cal major power factor if you hit your A zones. Only when you miss is minor caliber a scoring disadvantage.
