I am a huge fan of matching rimfire-centerfire guns,,,
So it was a no-brainer when I wanted a 22-9mm pair of pistols.
I decided not to mess with an adapter,,,
I went this route.
CZ-75B in 9mm,,,
CZ-75B Kadet in .22 LR,,,
Fantastic pistols that run any ammo.
Yesterday morning I took a young man shooting,,,
We ran 100 rounds of Tula steel case through the 9mm,,,
And close to 400 rounds of Federal Bulk Pack through the Kadet.
Not one stoppage of any kind.
