Is it the fact that it would get in the way of your grip? I worried about that too but was holding someone's LCP that had a CT laser and you didn't even notice. Obviously that's not a Shield so who knows what it would feel like. But if you're shopping at a brick and mortar shop I bet they'd pop a CT on either yours or their Shield and let you see what it feels like. If I were to replace my LaserMax I think I'd be like rbuzz and look at the ArmaLaser.
