Greetings and welcome to the forum. When looking for a 3" or thereabouts compact 357 Magnum you would be looking at a model 65 or 66.
These have gone through the roof lately with prime specimens bringing $500. to $800. on the auction sites these days.
Rightfully so, these K Magnum wonders are fantastic to shoot, and easy to carry.
Find one, buy it ,and you'll not regret it.
Good luck ,,Allen F.
