Looks like the Honor Defense, makers of Honor Guard single-stack 9mm, ceased operations. The gun media haven't noticed yet although it was perhaps 2 months since.
@valleyforge Honor Defense were in every glossy magazine of the day because one of their early models included a stand-off device, which protruded significantly more than e.g. guide rod on XD-S. Another single-stack 9mm from that era is FMK (the company still operates), and Rob Pincus' and Avidity Arms PD-10 (which apparently never shipped -- only prototypes existed). This whole category fell victim to SIG P365. I expect Kahr to join these failures any day now.
