I've been shooting quite a bit of pistol lately and my kids have shown a real interest in going with me. I'm not sure what the appropriate firearm would be to get them going, I have an 8 year old girl and 10 year old son and have a feeling it might be more for my daughter. I'm more of a Glock guy and don't really know what to start her off with, any good advise on possibly a .22 or.....?
