Not a deal breaker at all. Sounds like someone forgot to put some loctite on the guide rod threads when they assembled it. All you need to do is either snug it up with a hex-wrench if it's one of those types, or disassemble it, put some loctite on it, tighten it up, and assemble it. Also, the Para 14.40 is built on a P12 frame. Maybe the guy you got it from did convert it himself, but there was no need to.
