I'm looking at picking up a Springfield GI in stainless, and would like to add an extended safety, flat mainspring housing, and bob the hammer. I'm pretty much sold on the idea of this package, but before I pony up the dough I was wondering if another gun maker had an offering like this to look at? I want to be as close the the original GI specs as possible so the Milspec is out. I'm only having the mods done for shooting comfort. Thanks for the help!
