All newer models, yes.

But all K and N frames after only after ~ 1960 usually indicated by the model -1, but not every model.

To be fool proof, look for the 1/32" to 1/16" groove cut around the extractor rod just behind the knurled tip which denotes left hand thread.

And sometimes there's an "L" stamped on the cyl face to denote Left-Hand extractor rod threads.

All J frames.

All I frames with straight extractor rod knobs. Late 1940s Transitional models with pre war style large ‘barrel' shaped extractor rod knob can have right or left hand thread.
