Based on this one test, I'd say that you shot the HK & the Sig 320 a little better, but I'd probably run the test again.
I love the Sig Legion series & have the 229 Legion version as one of my regular carry guns, the other being a Beretta 92 Compact & sometimes a Commander sized 1911, but I like the mag capacity of the 9's.
The Legion grips are cut just right to fit my hand & the Legion 3D sights (if that's what you have) are really good, so of what you have, I'd take the 320, HK next, which is also a very good piece with a trigger better than most Glocks.
The 226 is a little too big for comfortable, everyday AIWB, which is what I usually use, but not sure what your church attire might be.
Good Luck...........all nice guns.

The Legions and the HK fit my hand the best but I need an instructor to tell me how to shoot that P226! The P320 is by far the most fun and I ordered an SRO to stick on that one.
And depending on the mail, this coming week I want to mount a dot on the P226 but need a filler plate.
