How accurate should a 4 inch revolver be?

[M3Stuart]

All my Smiths are more accurate than me. I don't know the measurements, but I normally keep everything in the black at 50' with all my 2, 2.5, 3 and 4 inchers when in single action. DA gets a little worse with more flyers. The 4 inchers do better, and the adj sights do better. Though my 64 4" is quite accurate. I also handload my .38's pretty weak with 158 gr LSWCs.

Bottom line; hold the target up against your chest - odds are that any of your hits would have 'eliminated the threat'. That's all I really care about.
