Like the title says what is the difference in the glocks made in Austria and the ones made in the US. I am pretty new to glock but have been carrying my 19 gen. 3 for a while and just noticed that it is a full made in Austria glock, was wondering what if any differences there were. I read online there isn't much but some forum said the finishes are different. Can any glock expert here educate me on the differences?
