An auto loader like the Remington 1100 trap would be a good idea, IMHO, if your wife plans on doing a lot of shooting, such as registered targets in trap. As previously said, it's important that it fit her well, but that can be accomplished with adjusting the length of the stock, adjustable buttplate, etc. The reduced recoil from an auto loader goes a long way toward preventing a flinch from developing. One ounce target loads are a good starting point; more than sufficient for 16 yard targets in trap. Wearing the most effective hearing protection available helps concentration; I used to wear both plugs and muffs. If she gets real serious, the shooting glasses with different shaded lenses make it easier to pick up orange targets against different colored backgrounds.
