I handled the 9mm version, which has the exact same dimensions as the 10mm, oddly enough.
I liked it! Liked the trigger, liked the grip angle, but the Hex Dragonfly sight DID NOT like my astigmatism. The red dot looked like a copy of the birthmark on Gorbachev's forehead.
I have a G29, a Gen 4 G23, and a Gen 5 G23. I am hoping the SA XD-M Elite in 10mm will replace them all as my usual carry gun in the woods, the hoods, and anywhere else I choose to carry. Searching on GB, looks like I can pick up a model ready for a red dot for $570. The Hex Dragonfly sells for $229 on Amazon, but gets bad reviews. But, it uses the Docter footprint. I would likely order a new SA optics ready, then order the sight of my choice that fits. Likely either the new Burris Fastfire IV, or the new Crimson Trace RAD.
