I've never had a single feeding or reliability issue with mine that I can recall. I got a smoking deal on FN SS197SR ammo, the blue tip Vmax stuff, shortly after I bought mine and that's all I've ever shot in it.I'm assuming your KelTec 22mag is a PMR30, what issues do you have with it that cause it to not run reliable for you? They're a fugly looking thing but I actually like shooting my PMR27 better then I do my FN Five Seven. I call mine a PMR27 because if I only load 27rnds in the mags it'll run the 30gr Vmax ammo flawlessly without a single hiccup. I don't know what issues you are having with yours but have you looked into any of the stuff MCarbo has for the PMR30's to see if that'll help your problem? https://www.mcarbo.com/kel-tec-pmr-30-accessories-upgrades
Like I mentioned before I don't recall ever having a single issue with my Mk2 version. My only complaint is the trigger could certainly be better but it sounds like the newer Mk3 like you're getting has a better/upgraded trigger in them. If you don't mind, once you get yours report back and tell me how you like it compared to your PMR30's and especially what the new trigger is like in the Mk3's. FN makes good stuff and they've been steadily improving their five sevens over the years with each new version so this newest model should be the best one yet and you'll likely really like it.
