My dream 29 has never been made.
It is a 29-4 with a 5 shot cylinder to get the locking nothes between the chambers.

Otherwise, the best 29-2 is a 57 nodash because the tiny difference is just what the N-frame needs to be long lasting. I replaced my 29-2 with a 57 nodash for IHMSA silhouette back in he days. The 57 held together much better. Both revolvers were shot with reduced magnum loads, just enough to topple the rams.
