I've been waiting for the Glock 43x to:
1. Add RMR capability
2. Light mount/rail designed into the frame (I know, available in Europe already)

This Hellcat does both and does both right now. I'm interested. Shot Show is Jan. 2020. I may give Glock that long to update the 43x and that will also give consumers a chance to put rounds thru the SA Hellcat and assess weak points and/or teething issues.

Note: My LGS says he expects to see them in his store within 2 weeks.
