You know the funny thing is that series of guns were basically given away on gbroker for about ten years. I clipped two 620’s for under $500 between 2013-15. Both times I was the only bid. When they show up now they are usually offered around $7xx on and hammer somewhere close to that. They typically seem to be high condition. 619s and 520’s are harder to come by than 620’s. According S&W marketing 620 was 66 replacement, 619 = 65 replacement, 520 was 620 in matte black finish and scandium cylinder with hiviz front sight, v notch rear blade. This is not to be confused with the old N frame 520.
For what it’s worth, these early two piece L frames have the reputation for shooting lights-out. I bought two 620’s incase something ever happens to one of them. I use the primary for testing hand loads because I shoot consistently well with it. That’s out of stable of S&W’s dating from 1951 to current. I bought the first because I wanted an ejector shroud L frames shoot and didn’t want to pony up for 686 Mountain Gun, especially when 620’s were so relatively cheap. Upon realizing the 620’s performance, I bought a second one.
