There was a small group buy on Weaponeer a couple years ago. I passed only because the caliber could not be confirmed. Some guys got 9 x 19 and some got the advertised 9 x 23 ( Which I wanted).
Most of these were pretty rough kits w/ missing parts. quite a few guys were pissed & sent them back.
I have checked with MGS several times over the past two years and they are always out. But seem to have one or two now & then. Returns? I don't know.
My interest is the odball 9 x 23 Largo caliber.
But anyhow I am familiar with this kit from the group buy.
