What I am looking for is not how great this firearm is (that's easy to get) but rather feedback on things you don't like and things you wished you knew before buying one.
Hi, and welcome!
I have the Mk II version of the gun you shot. I don't need a replacement at this time, but if I did, I'd probably look around for another Mk II before jumping into the Mk III.
I like the new mag release, but other than that, I see no "operational" differences worth noting between the two models.
I don't like the new LCI. Seems I remember reading here of some problems w/ the first one, and of a change to cure those problems (something about the original metal one causing unintended discharges on return to battery so a plastic part was substituted? You'll want to do some research to make sure I'm not giving you bad info.) I guess the "problem" is cured, but I don't think the LCI design is a good one to start with, and 'specially don't like seeing a "bandage" on a bad design. I'd think keeping a couple of spare LCIs in the box might not be a bad idea.
Internally, I'm not really familiar w/ the Mk III yet. My brother in law just picked one up, and we took it to the range a couple of days ago. It functioned perfectly thru its first 200 rds, using CCI Blazers (which BTW, MY Mk II isn't fond of, so remember you'll need to find the ammo YOUR gun likes! Common w/ most .22s, not a big worrisome item.)
But he hadn't field stripped it yet, so I don't know how much more of an adventure it is than the Mk II he had years ago. Biggest "problem" w/ the Mk II stripping drill is you HAVE to do it EXACTLY as the book specifies, else you'll think you're never gonna get things back together and working. I assume that's the case w/ the Mk III, too.
FWIW, the magazine for the Mk III is "unique" because of its new mag release slot. It does seem to be "backwards compatible" w/ the Mk II (my BIL's snaps right into my gun, but we didn't function fire it), but the Mk II mags aren't "forward compatible." Probably not a big deal. If my theory's correct, I wouldn't be surprised to see only a single magazine on the shelves soon, sold as a "Fits Mk II and Mk III" part.
Seems to me the "lawyering up" of the Mk III adds no real value, so I'll suggest the change in mag release position is the only "improvement" on the Mk II for most actual shooters.
Opinions will vary, of course!
