New Vaquero grip frames interchangeble to NM Blackhawk?

Are New Vaquero grip frames interchangeble to NM Blackhawk? I think not but just wanted to verify. Thanks

In general,, yes they will interchange. The screw hole pattern is the same.

HOWEVER, It also depends upon how "new" each one is. Older grip frames,, have "ears" that insert into "slots" of the older main frames. And newer frames do not have these slots, or ears.

Thanks Contender!
