Shot the Glock 45 and Shadow System briefly...sans light. They felt very similar. IDK what my malfunction was the first day? Just shot a few groups slow fire. Grouping was very close...maybe a smidge better for the SS.
Here's 10 rounds with the 45 at 7'ish rounds...
And the SS...same deal
Then shot at 100 briefly...the 45 did better. Probably because I'm more used to the trigger.
