There are too many stories around regarding performance (accuracy) issues with the Micro Hunter. I may not have believed them except for the fact that I lived one myself. After probably a couple thousand rounds trying to address the issue of ~20% flyers when using the OEM mag (working with RAW directly via email), i finally got to the point where I could get repeated flyer-free groups - but only when using a single shot loader. At that point RAW offered to bring the gun back to their shop. That was last October. I finally got it back in Feb. They had done some polishing, rebuilt the reg (although velocity spreads had always been tight), and had replaced the magazine with a new OEM type which looks more like a 3D printed one (no longer black back with clear face). And - the returned gun is as bad or worse from an accuracy standpoint. A couple of things in its favor? Like said above the reg seems to perform very well, and the trigger is RAW sublime. It is light and handy - but that is all pretty meaningless if it is not accurate.
I offered it up to a friend, who had gone through the whole dance with his own Micro Hunter previously, and was finally able to get it shooting right by sending it to Martin instead of to RAW. I gave it to him as I really didn't want to see it any more.
I would imagine that the mini is maybe something which RAW understands better as it is more similar to their standard HM1000's. But the Micro is something which I just cannot recommend as it seems like maybe it was launched prematurely before all the bugs were worked out, and RAW doesn't even seem to understand the gun.
Fact is that after this debacle, I'm just going to stay away from anything RAW for a while.
YMMV
