Remington 1100 is my go to gun for new shooters. Gotta love a gas gun for taming recoil and won’t break the bank.
Look for an older 2 3/4 chambered 26” ribbed barrel gun with a more open choke, IC preferred for skeet, or modified will make you be a little more precise.
Get the stock shortened by somebody who knows what he is doing, too many new shooters experience pain from recoil because the stock is too long and forces them into an improper gun mount. My guess would be somewhere around 13 1/2” LOP.
If that is too heavy look for a Remington 11-87 Compact in 20 ga. to get you going. Most girls and kids of smaller stature can lift that sweetheart with comfort and after a couple of months they will have built up the strength to handle a 12 ga.
Have fun on your journey!
