I use both, I do like the splatter for instant feedback when I’m experiencing problems.
For instance with my Shield at distances of 14ft or greater my shots are low left yet with both my M&P2.0c and HK P2000SK I don’t experience this. Kept trying to figure out, was it grip, sight alignment, rushing etc.
A guy at the range saw me getting frustrated and suggested I align the bottom of the front sight with the top of the rear sight, problem solved. Come to find out this is a known issue with the S&W Bodyguard, but not as well known with the Shield. Debating on whether to send it in to S&W on just continue with the adjusted sight alignment.
