I've got a 20" model 92 in .44 mag, one of the older ones imported by Interarms. It does equally well with .44 special as it does with full power mag loads.
You don't give the bullet weights of the ones you have, so I'm assuming they're probably 240 grain bullets. You might want to verify that they will expand as intended with the lighter loads. Granted, you'd be shooting them in a carbine with a closed breach and longer barrel than a revolver, so you'll pick up some velocity from that, but will it be enough for reliable expansion for a bullet that's intended for expansion at 1200+ fps? It would be good to verify.
