Grendel has been gone for quite some time. None of their products were well received, but they were cheap. My experience is that you should sell them, not buy. Most of their brain trust migrated to Kel Tec. That's why there is such a family resemblance. I dumped one of their P-10 at the start of the obummer reign for more than twice what I paid new in 1990. And it was still pocket change. Parts are hard to come by.
