It's never a bad thing to have a .22 for practice,,,
It's never a bad thing to have a .22 for practice,,,
And to have one that is identical or close to your carry gun is even better.
Now having said that none of the .22 pistols you mentioned,,,
Have the same action as your SR9c.
Of the three .22's the SR-22 would be closest in size and shape,,,
But the SR9c is a striker fired pistol.
It's essentially a hammerless DAO,,,
The SR-22 is a SA/DA with external hammer.
Even so, I would choose it over the others due to that similarity in size/shape.
I own all three of the .22's you mentioned,,,
While the 22/45 and the Buckmark are fine shooters,,,
If your purpose is to use it as an understudy the SR-22 is the better choice.
Just my humble opinion.
