 Among the many changes, Browning redesigned the grip and frame safety, simplifying their internal design and multi-function while still maintaining their intended purpose. Browning noted that this “//manually operated combined slide-lock and hammer-lock//” would now make the gun “//positively safe against discharge//” despite the condition in which the gun was being carried by soldiers in the field. Among the many changes, Browning redesigned the grip and frame safety, simplifying their internal design and multi-function while still maintaining their intended purpose.

-<note>Not fully satisfied with the safety that Browning designed into his 1913 version, during the series of changes that Colt made later, they added a firing pin block safety (aka a "drop safety") in 1983. This was one of the changes made in the [[https://gunbelts.com/blog/series-80-1911/|Series 80 model]]. A pivoting link is actuated by the trigger pull, pushing the firing pin block up and unblocking the firing pin. Thus, the firing pin can only move IF the trigger is pulled. Many critics of this change (including some manufacturers) modify their 1911 pistols to better align with the Series 70 model.</note>+<WRAP center round info 40%>

 To achieve the goal of allowing the gun to be disassembled without any tools, one of the ways this was accomplished was by simply redesigning the spring and its housing between the frame safety and the slide lock. By allowing the now-slightly-bent spring to essentially hold itself in tension between the safety and lock, Browning was able to eliminate a locking pin and frame stud. Fewer parts meant faster production, less cost, and easier assembly and disassembly. To achieve the goal of allowing the gun to be disassembled without any tools, one of the ways this was accomplished was by simply redesigning the spring and its housing between the frame safety and the slide lock.
