Does this fit the s&w m&p 5.7

5.7 Rock, yes it will fit directly and flush. You can do a quick search online and check some examples for reference. Look up s&w 5.7 holosun. Hope this helps.

Are these 100% authentic Holosun optics? There are way too many posts about people receiving terrible knock offs or dots that just don't work properly

We understand your frustration, and we want to assure you that Holosun is actively monitoring and investigating instances of fraud or malicious sellers offering counterfeit Ingenium products. Holosun has partnered with Amazon in their transparency program, which requires every authorized seller to provide a Transparency code sticker (QR code) with each optic sold. When you receive your item, please check for this code sticker, as it will verify the authenticity of the Holosun product. If you suspect that the item you received is not genuine, we encourage you to return it for a full refund and consider reordering from a different seller. We hope this information is helpful to you.

Will this fit Glock 47?

If you have the G47 MOS model, you will need an adapter plate to direct fit the optic. This optic uses RMSc footprint. Hope this helps.

on an MOS gun with an adapter plate, yes. Otherwise, for non MOS guns, you need to have your slide milled.
