looking at a first revolver

[kmyers]

The L frame .357 would be my first choice.

What does the number after the dash mean? Like XXX-2

The x is the dash number designation. Original issue is called by most a no dash.
Then as engineering changes come along the designation of the model # is changed for instance model 29, 29-1, 29-2 etc up to current production #.
Like on on 4506 there is also a 4506-1 and a 39-2 in semi auto world.

Of those you list, and wanting the adustable, versus the fixed, sights - then your best choice is the 686 for $450.

Actually, it's your only choice based on what you said you wanted.

Just FYI; the Ruger 5 shot DA revolvers are the SP101's (probably), the 6 shooters are the GP100's - they make both. Plus a whole sleuth of single action revolvers that I know nothing about.
