Congrats!
An 1899 in 22HP is called for, I think.
I did that for my youngest nephew a long time ago. 22 Savage HP and with a little help from folks on this forum I got an abused 99 buttstock and cut it down and refinished and my 6 year old nephew did the rest. The 22 HP is great gun to get your first doe. Good luck and congrats on being GrandPA
