I would like to see a
K-frame 7-shot or a N-frame 8-shot (or both)
offered in 9mm!

SInce S&W never built a K-frame 7 shot K before how would that be possible with a 9MM that has virtually the same bore/bullet dia.

N-fraem 9MM - why? when the PC center builds a .357 Mag/.38 Spcl cut for full moon clips or don't use the clips and lesser ballistics, so where is the interest market
segment wise?

Ask for an L-frame 7 shooter and you make a bit of sense with more reliable ejection of brass

I have a 686P and one or two empties hang up on the cyl. thumb release consistently

I meant an L-frame not K. Same as current 686+.

They've already made the 627 8-shot in .38 Super. You can shoot 9mm in that one also. I doubt you'll see a 7-shot 9mm L-frame. Most wheelgun competitions wouldn't allow it.
