Shield- The gun weighs 19 oz and has a reasonable trigger pull (6.5 lbs advertised) and there are aftermarket night sights for it. So, you would be most likely to hit what you're aiming at with this.
How does accuracy diminish from lack of night sites? IMO, small guns like these are point shooters and sites are a moot point, especially night sites.
