I'm leery of PO's when it comes to reliability. Many 1911 gunsmiths won't work on them and I don't blame them. When you charge a set price per job, and an out-of-spec gun ends up taking 3x longer than it should to work on, cuts into your profits.
With that being said, before PO came out with the Warthog they had the plain version, the P10. I ordered a stainless one, hand-checkered it, installed tritium sights, ambi-safety, steel MSH, all new ignition parts, got rid of the Series 80 stuff. When I was all done, it looked identical to the later incarnation they came out with; the Warthog.
Mine was perfectly reliable and one of the most accurate handguns I've ever owned. Scary accurate at 25" yards, especially with the short sight radius. I've owned several 5" 1911's that didn't shoot near as tight.
Traded it to a buddy for something I wanted/needed more. Can't even remember what it was anymore. He carried it for several years as his regular CCW.
