Yes, they did. There are some out in the wild as I type this. One is actually for sale over on the FALFiles sight. General consensus is they are way over priced when considering the availability of the AP5's, which is made by MKE.I guess they didnt got this to fruition?
I purchased a zf5p. A little rough first time out. Think it needs a better break in. Haven’t had time to get back to the range. Took home cleaned and lubed. Will chime back in next weekend.
