Most people have limited experience with numerous kinds of guns. EDM has researched Parkers well but is childish in his knowledge of other guns, but still likes to tell everyone they are the best ever. He doesn't even know what a Lindner is. Add to this the infamous word "opinion". Each person has his preference, even "experts". Trevallion even likes Purdeys (what a maroon!)

You simply have to learn to judge the opinion from the fact.
