Looking to buy an 8-shot S&W 38/.357 revolver in one of the variants released over the years.

Looking for a lesser cost model in good or better shape. Will consider most any option, though.

Edit: looking for 4" or longer.

I have a "Bloodwork" 8 shot Model (with the lock). I bought it new and shot 100rds throught it. Have the box, papers and the rest. Might fit your parameters. If interested, pls email me @ cypresselectric@msn.com to discuss the particulars. Otherwise, best wishes on your search.

Are all bloodworks snubbies?

I'm looking for a 4" or longer.

Yes, The UDR ( Bloodwork Gun) is an 8 shot "snubby". It has an odd barrel length that I can't remember for the life of me @ the moment.
Hope you find your 4 incher.
