Love my Springfield milspec. I like my new Springfield Ronin. Lately, gravitating back to the milspec for it's simple no nonsense feel and look. Does that make sense? Not counting custom guns, at what Springfield model upgrade would I actually see an increased reliability (from an engineering stand point)? In other words.. I don't need the bells and whistles. If I recall correctly, I think someone posted earlier that it might be the TRP. And that the other models in between won't really add any difference in the reliability to the already reliable milspec. Is this correct?
