Hey Duke,
My bf and I are in the same boat. We got into trap shooting at our local club at pretty much the exact same time. Being a female myself, here is my advice.
I went to a gun store and tried positioning a shotgun without knowing names or prices. I found what felt good in terms of weight, tried it out for a week of trap shooting and took it in to have the stock shortened for a meer $40.
Another suggestion...a shoulder pad. Being a smaller woman, I was being bruised quite easily. I found that I could not find a vest with padding in Canada via the internet (including Bass Pro and Cabela's). I just got a pad that can be strapped to my shoulder and it gives me just that little more confidence to shoot in my own style and with consistency.
Hope this helps.
