I have had a J22 for years.
My wife kept it in her office til she got a .38.
My sister carried it fishing on the river.
I carried in the front pocket of my field jacket on the mountain.
Once a year, I take the four magazines, fire the ammo, clean the gun
and reload the magazines with fresh ammo.
As long as I use CCI Stinger, it functions 100%.
It also does well with Aguila SSS 60 grain bullet.
I dont expect to shoot it a thousand rounds a year and last twenty+ years like my Ruger MarkII.
For backup or when the alternative would be no gun, it serves well.
Some J22s are crap especially ones that have been abused by previous owners, but there are good serviceable J22s out there.
