I know some worry when giving a semi auto to a youngster and I somewhat understand that.. And every individual is different.. I have no problem with them learning on a semi..Just watch them closely. And if a semi bothers you all that much..Just load one in the magazine..It is then a single shot.. I know when my kids were young..They got bored really quick with a single shot cricket I had for them..Still have it actually..
Most youngster catch on very quick.. Other than a Revolver, the options are pretty limited for a single shot..
My Grandkids have been shooting my Beretta 70S. Very, very ultra reliable.. Not too large for their hands..Drawback is they are not really readily available, or that cheap either..
I bought the Wife a TX22..Reiable and not too expensive, she is worth it ya know,LOL
