years back i saw a smith and wesson 637 airweight with the two and a half inch barrel which i thought was kinda rare...i should have bought it but i did not... i was at a gun show the other day and i saw another one.... i did an equal trade with my new unfired lcr 9mm.... the 637 is cool becuase it has the full length ejector rod and the longer barrel..... did i do good with this trade ???
