Bennie, This firearm has a de cocker/safety combo lever. Much of the construction and parts are the same as original colt. RIA used original blueprints and specs. RIA made 1911s for the US military back in WWII -The US government gave a copy of the original Colt 1911 blueprints to the RIA company back then so they could make these pistols for the US troops in WWII. That same factory that was used in the Philippines to make those 1911s is the same factory that is being used today and RIA still uses those same old Colt blueprints to make their 1911s. So, although these pistols have the small RIA logo on the rear of the slide, these 1911s are exact copies of the original Colt 1911s. This is just like a full sized GI style 1911 but is .75 inches shorter than the full sized 5 inch version. The big difference here is the MS has a full length guide rod and a bull barrel and no barrel bushing or recoil spring plug. As a result, the take-down/ field strip process is a little different than your standard issue 1911 and in some ways a bit more difficult. But don't let that scare you away. I highly recommend that you use a bent paper clip or an Allen-wrench to help you with field-stripping this pistol.
