So I have one of the 3" 24-3 revolvers...I think it's one of the Lew Horton guns, but don't box or paperwork. Anyway, I've seen where it was referred to as the first N-frame factory round butt...but then I've seen it described as a "K-frame" round butt on an N-frame. If I'm looking for replacement stocks/grips (don't have the original wood grips, unfortunately), do I buy N-frame round butt or K/L-frame grips? Thanks in advance for any help!
