I-dots are very nice, but as you can see the rear sight has almost no vertical edge to push on. There is a VERY thin edge at the bottom, that's it. Makes it difficult to install, even with a sight pusher.

I had the Ameri-Glo I-Dot SW-141 (same as the OP listed) put on my Shield 2 months ago. The LGS installs sights cheap if you buy from him, so I had him order me a set. His sight pusher was for a standard M&P, not the Shield. He had to install them the old fashioned way, with a brass punch. He said the old sights were harder to get off than putting the new ones on. Not a bad $10 install.
So far, they are okay. I wanted the I-dot set-up since I'm used to Heinie Straight Eight sights. I'm not used to the white dot outline. I considered the Ameri-Glo Hackathorn set, but didn't want an orange front. Still, better than stock sights.
