I'm considering getting my husband a new gun for Christmas. I don't know much about guns but I know he is wanting to broaden the variety of his collection. To give you an idea of his likes, he has a shotgun and rifle, and a few handguns, including a Sig Sauer P229, Springfield XDM, and Beretta something (it's a 9mm, but I'm not sure of the model) One thing he does not have is a revolver, but when we browse guns at stores, he does mention it would be a fun gun to have. Also, he is active duty military, so I thought it might be cool to get him something with military history, but I'm open to any suggestions. Thanks in advance for your advice!
