I have owend both my pm5 wasnt ultralight framed but still prefered it over my pmr handled really wellA PMR is more recent and up to date in my opinion, and they are great guns, and with a PMR you wouldnt even need to get a UL frame, since the stock pmr/pm7 board in it has semi, psp and mil already on it, and plus the UL actually ways more than the stock frame already fitted on the PMR. And theres plenty of aftermarket triggers for the PMR if you dont like the stock one, the stock trigger is either a love or hate trigger, some ballers love it, some hate it.
