Shield would be mo better for gaming. There has been chatter about an improved Shield model for a while, but nothing has happened that I am aware of.
Guy ran a Shield through the TPC class last week, including on a day with crazy wind and blowing sand. He said the zero held but the dot appeared to move within the window. I didn’t see it, just repeating what he said. I heard Glock mounted a number of them on MOS demo guns and they haven’t broken yet. I love how low they sit and how you can use regular height sights as BUIS with them.
