Ok I know company's want to improve there products and after 10 years was probably do. However when you take one step forward you shouldn't go back three.1) why would you put a loaded chamber indicator on any of your guns? If you don't know you have a round in the chamber then stop shooting cause it's time.2) thumb safety W.T.F. all I can say about this..3) slide serrations not useful and don't really look good kinda like you started them then decided to have a slide cut out and you left what was already there.. I'll stick with the original... missed it by that much!!!
