Overall I prefer the G19. Both are completely stock. The shield is comfortable except the with the 7 round mag. Got to get more 8 round mags. I'm not a fan of finger groves on my grips. So both are good on that front. The simple fact that the G19 is double stack and thicker makes it more comfortable. One thing I don't like about the shield is the slide lock. It's too damn stiff to be a good slide release.Just curious. How do you like the grip on the Shield compared to your G19? Or did you modify the Shield grip.
