One of the items packed with the brochure was my mint copy of Cooper on Handguns, 1st edition with the red cover, sealed in a plastic bag.
The M-S Safari 1911 had a concave trigger guard, not a square one like Swenson's. Both illistrate that the normal way of gripping, which Cooper called a "natural 5 finger grip" was expected to place the index finger in front of the trigger: Strong hand finger inside the guard, weak hand finger around the front of the guard. Swenson's square guard was usually checkered (30 lines) to give better purchse. The Safari concave guard took it a step further and mimicked the shape of the trigger.
