Due to arthritic issues I had to rid myself of my all steel heavyweight 9mm 1911 that weighed in at 44 ounces unloaded. My issue was holding it for more that 30 seconds my hand would shake thereby reducing my accuracy to a great degree. After a lot of searching I found a Kimber Aegis that weighed in at a light 31 ounces which helped immensely in improving my accuracy. I went further by replacing the wooden grips with slim polymer grips and replacing the end cap and guide rod with GI spec parts. The total weight savings has now brought the gun down to 29.3 ounces unloaded. The difference for these tired hands was remarkable. I'm now back to shooting accuracy like the good old days. Saving almost a full pound has made a significant improvement.
