Thanks for the kind words.
Those times are definitely after a warm up. I've been trying to find a grip that works well on the 45C, and after watching this video, figured out that closing my support hand fingers first, and then bringing the palm onto the grip, makes a very big difference in maintaining control and not shifting my grip during continuous fire. Gripping the gun hard with both hands also has helped me track the front sight better, though i can't explain how thats related to the grip.

Brief update. Decided to stay with the 45C.
At the range today:
What range in MA lets you draw from the holster?
