Any thoughts on the S&W 620? Looks like a 357 version of the Mountain Gun. Can’t find much about it.
S&W 620
- Thread starter Fish4bass101
- Start date
First, the 620 does not have a Mountain Gun's classic shaped light weight barrel. However, they did dump the standard full lug so 620s are lighter than standard production 4" 686s.
The 620 was one of S&W's early "two piece barrel" revolvers. Its barrel is under tension between the frame threads and its muzzle flange bearing on the front of the shroud. Some members believe that assembly creates the most accurate revolvers S&W has ever manufactured. That's the good news. The bad is that removing the barrel is a factory only job and damages the barrel. That's because a wrench that has the reverse shape of the rifling is inserted in the muzzle to engage the barrel. That's also why the barrels have a short length of rifling reamed out after assembly.
The 620 was not on the market for long so in addition to their potential accuracy they may turn out to be a sought after collectors' item.

The 620 shoots so well I bought a second one LNIB just incase something happen to my primary. I have a two safes full of old k and n frame Smiths and the 620 is the best shooter in the bunch. The 620, 619 (fixed sight version of a 620) and 2005 520 are some of the most over looked revolvers in the S&W line up.
The 620 and 619 were supposed to replace the 66 and 65 respectively. There were some noted issues with barrel failure where the flange at the muzzle would separate. It happened to one of our forum members who documented with pictures. Mine has at least 8k through it and still going strong. I bought it because they can be had for less than 1/2 what a 357 Mountain Gun commands. Hell, I bought two 620’s for less than Lipsys 357 mountain gun...The 620 and 627-5 were the last of conventional ejector shroud stainless guns Smith made. I had to have both.
My daily shooter 620 is what I use to accuracy test my hand loads and would be one of the last guns I get rid of, if I had to.
I cant really do this as consistantly with my other guns...double action 10 yards.

A few years back I decided to see what my 620 was capable of. Mounted a 1.75X Nikon Handgun scope to it and spent 6 weeks practicing twice a week.
End result is the target below. Note, I am not the greatest shot in the world by any stretch, I suspect the 620 may be capable of sub 1 MOA accuracy in better hands than mine. As it is the 4 on the left spanned 7/8 inch center to center.
The group on left are the first 4 fired at 50 yards, shot far right is #5 when I snatched the trigger, and the 2 stacked to the right are when the rear mount on the scope shot loose. Unfortunately these were the last 7 rounds I had with me. Hindsight lesson learned is that tightening the scope mount with a quarter just wasn't adequate, should have used pliers on that quarter.
