My answer is no. Mainly because I've never bought a gun that I didn't research and learn about ahead of time. I knew what I was getting and whether or not it was going to be a good gun for me. I've NEVER bought a gun on impulse. Even when I bought inexpensive guns like a Hi-Point, I researched it for a while. And then, when the opportunity presented itself, I knew already what I was buying. This includes handling, feeling, dry firing, etc... such guns during the learning process. I appreciate every gun that I've bought. Whether it's my SA 1911A1, Kimber, Dan Wesson, S&W, CZ, Walther, or all my other guns.... down to my lowly Hi-Point that some people look down on. I appreciate and enjoy each of them all for their purpose. I've lowered the number of guns I now have. Down to about 20 guns. But I have a purpose for each gun. And because of that, I can appreciate each gun for it's purpose and uniquness.
I will say however that I do on occasion buy guns for the soul purpose of using them as trading material. I.e. I picked up a glock 27 in 40sw a couple months ago that someone needed money for, and the pawn shop was going to rape him. I couldn't do much better, but at least I didn't use a handful of sand on him. Anyway, the gun is too small for me to handle and I don't care for 40sw at all, so I held onto it for about a month and unloaded it. I never even shot it. That's the closest I've come to having a gun that I didn't thoroughly research and know what I was getting.
