I wouldn't bother with an ergonomic grip until you've been shooting long enough to know how to properly carve it so it matches your natural point of aim.
If you prefer a heavy gun, Ruger. If you have big hands, a Smith 41. If you prefer a smaller grip, lighter gun, go for an old High Standard...
It's a pistol.
This happens often with target guns. The trigger gets out of adjustment, or the breech face gets worn down and they double, or can expend the whole mag. No big deal. Just re-adjust the trigger, or fix the breech face.
