Same as yours, most likely--reading about it on the Internet. But I plan to get one as my next gun purchase. I write books and try to buy a gun with each big advance or royalty check as sort of a keepsake. I have one of each coming late this winter and definitely plan on getting a PLR and maybe a 6.8 upper for my AR (or maybe just pay off my pickup).
From what I've read, and from personal experience with Kel-Tec products, I believe the PLR is the only completely reliable .233-caliber pistol on the market, at least out of the box. I've never seen a Stoner-type pistol that was reliable out of the box, and in fact have never seen a reliable AR pistol with my own eyes. The ones I've seen at various ranges are all troublesome jam-O-matics, but I've read about people making them reliable after dumping some money into them. By the same token, I've never heard of a single instance of the PLR jamming.
I'm serious about carrying the PLR. I plan to buy one primarily as a truck gun, but am thinking about the 3-point sling option for carrying it on motorcycle. I used to love to ride dirtbike around my dad's farm and hunt gophers with a handgun. The PLR strikes me as an epic gopher slayer.
