Well, you've already found out that trap shooters are friendly, welcoming and helpful and you have lots of good clubs not too far away. As already mentioned, at this stage in your shooting curve you don't need a perfectly fitting gun, although it's a great goal you haven't yet had enough experience to get the most benefit from it. You need to shoot as often as you can and develop good habits and shoot with purpose. For instance, many clubs will happily allow one or several shooters to work on one problem target repeatedly, such as shooting 5-10-25 consecutive shots from one station or with the machine locked to give the same presentation repeatedly. This can't be done in conjunction with a regular round of trap of course but there is often slack time available for shooters to work on problems such as hard rights from station five for some. If for instance it seems that you just can't hit these or miss far too many "simple" straightaways, the best cure is to shoot this target repeatedly until you can hit it consistently. Many clubs have one or more beginner's trap shooting clinics during the year and these are frequently attended by multiple women. These are typically a two day weekend affair with mornings spent in the classroom and afternoons on the range with one on one coaching. There is usually a nominal cost for these clinics to cover expenses to the club, instructors frequently donate their time. Check to see if one of your nearby clubs will be offering this for this summer, you will advance farther in two days than you will all summer by just shooting. If this Covid thing doesn't get in the way our club will run one of these clinics later this summer and it might be within your reach. Contact me for details.
A little on gun fit, what to look for, but remember, it isn't critical for you at this stage.
You must determine your master eye, right, left or neutral in the beginning, it can forestall a lot of grief later.
Most women in general, compared to men require -
Shorter stock, 5'6"-5"8", usually about 14"-14 1/4" length of pull
5'4"-5'6", usually about 13 3/4-14" length of pull
5'-5'4", usually about 13 - 13 3/4" length of pull
Higher comb, such as Monte Carlo type. This is built into some trap guns but not field guns. The usual modification to get this is to add an adjustable comb and/or a fully adjustable butt pad which can also adjust for length of pull.
Slimmer stock and forend
Tighter grip, putting the hand closer to the trigger.
Any good solid 7-71/2 pound reliable gun fitted with a fully adjustable recoil pad ( not a recoil reducer) should serve you well fot the first few years, maybe much longer. Many women stay with singles, not shooting doubles, and very many of these eventually settle on a Browning BT-99, usually with an adjustable recoil pad and win lots of matches. Shoot lots, shoot with purpose, break 'em all!
