I had 4 colt woodsman, as well as hi standards and sw 41's . The colt wooodsman is a close copy of the early hi standard model A & B with some improvements.
Over the years the colt wooodsman stayed close to its original design thru out its production.
Where the S&W 41 and Hi Standard citations, continued to evolve over the years into a more versital gun with interchangable barrels, sight options and gun configurations.
Talk to any 22lr bulls eye shooters and they will tell you that the Hi Standard Citation and the S&W 41 dominated the field for the last 40 yrs.
The Colt is a good gun, but it failed to keep up with the competition and not many shooters used them.
