I was recently looking at ballistic shield and came across different models on rtstactical. The website details the shields' protection levels and weights. I'm not buying a shield myself, but I was interested because I work alongside a team that uses similar devices in training. I also read on the forum that the handle shape is important to consider, as it really impacts comfort when holding it for long periods. The website offers several formats, so you can compare. If you want, check out the specifications; they're pretty clear. I think it's always helpful to look at the actual specifications, not just photos.
