Gladius caliber change?

[ShaneMeyer]

i have a hatsan gladius in .22 long version. Wondering what would have to be done to convert it to a .25 caliber. Thanks in advance

I'd be curious to know if Hatsan will even sell you the parts necessary for the convert.

Reachout to BWALTON. He would let you know what would be involved.

No way to change the caliber without changing all the major parts, ie breech, barrel, probe which would be more expensive than buying the different caliber.
