For the longest time it was a Wilkinson Arms Sherry .22.
Surprising quality, just large enough I could actually shoot it.

I actually wore it out, shooting it.
Wish I could find another at a reasonable price.

The little Erma .22’s aren’t bad, also imported as the Iver Johnson PX (PK?) 22,
memory fails me, this late.

The older Walther PP, PPK and PPKs .22’s could be decent trail guns, and passable defense guns (center fire is better), but the new ones are junk. Mere shadows of their former quality.

I refuse to carry a .22 anymore where defense may be a possibility, .32’s are available that fill that bill more effectively and reliabily. I’ve had enough misfires over the years to ever depend on one for my life again.
