It's not that I think my Shield is inaccurate but I've found the 4" Compact I got later is more accurate, at least for me. Part of that is probably the longer barrel and part of it is the bigger grip. The Shield is fine, the Compact is just better. I'm comfortable with either for EDC.

I can put every round center mass from 10 yds which is what I normally shoot with either gun but the groups will be tighter with the Compact.

Now if I go longer range the Compact is clearly better. I shot both from 25 yds and at that distance the Compact still gets the job done but with the Shield some of my shots miss the target completely.
