I am in my 80's and new to guns...I finally have bought two pistols...a GSG 1911 .22lr and a FNS-9....can I use any 22lr ammunition in my pistol....There are sometimes specified for rifle and sometimes it says for handgun in the advertisements...how can I tell what is good for my GSG 1911 pistol....I intend to use my 22lr extensively for target practice before using the FNS-9. The FNS-9 I recently treated with Froglube and the 22lr is having a fiber optic sight installed....Any suggestions to a newbie on any pistol subject will be greatly appreciated...Thanks....by the way ..guns are a very interesting subject to learn and the few times I was at the indoor range I really enjoyed it.....Frank
