What ever you do, don't base your selection on their descriptions and maybe not on their pictures either. I went there first time I bought from them and looked at numerous hammer doubles and revolvers I had selected from their descriptions and pictures. Nearly all had some defect that made them unacceptable, sometimes major problems. I did find a really nice Husqvarna hammer double that I would not have picked based on pics and words. Of course, with bird guns, handling qualities are critical, something that cannot be done remotely.
What I have done a few times, as have many others, is call and ask someone there to take gun(s) of interest in hand and answer your questions. This has saved me from guns with bad problems but, has still left undetected more minor problems. The two kinds of guns they seem to know least about is hammer doubles and rolling block rifles.
