There are many manufacturers that produce guns for women nowadays so that could be an option just do a search, not sure what your budget is, another option would be a youth model which would have a shorter shock and may fit your wife better. Best thing to do is go to a gun store or large store like cabelas or bass pro and have her shoulder some guns to see what fits her best. Regarding action type, the semi-autos and pumps would typically be the heaviest, unless you get a lightweight model, the break actions are generally lighter but with that can come more of a recoil punch. You can mitigate some of the recoil by what type of shotgun shell you are going to use. I think the 20 gauge would be your best bet, saves on weight and is more then enough to bring down the birds your viszla would be pointing.My wife of 25 years has been joining my 3 year old Viszla and myself in the field for our pheasant hunts just to take pictures and walk. She loves the exercise (we walk a lot). She signed up for Hunter's Safety and has expressed interest in carrying a gun and hunting now. I am thinking that nothing says "I love you!" but a shotgun present for Valentine's Day!
Any suggestions on what you would recommend? 12 gauge/20 gauge, Length of barrel, Pump, Semi or O/U
It may help if you know she is an athletic 5'4". For those concerned about my choice of Valentine's gift ideas I have to let you know that while I am a country boy I am not stupid so I will wait until the snow melts. I just don't have a lot of experience with different types of shotguns.
