For people wishing Colt offered more Series 70 guns, there is news. They are now offering two new models -- the S70 Level I and Level II. These look to be fairly straight-forward pistols with sights and safeties upgraded over the standard models. For non-tritium sights I still prefer the retro style, but the new models are equipped with Novaks with tritium on the Level II.
This makes four Series 70 models now offered by Colt:
S70 Repro Model (I own one which is overall my favorite .45)
S70 Gold Cup National Match (I own one)
S70 Level I
S70 Level II
