I have an older M41 that I used for Bullseye. It was accurate; however, a Marvel conversion (from before Marvel offered two versions) on top of one of my 1911 frames is more accurate. The test target that came with my Marvel measured under 0.75" at fifty yards. The trigger on the M41, while superb for a production pistol, is not as clean as a tuned 1911. The Marvel/1911 combo also offers the advanatge of using one platform for all of the Bullseye events.
In other events, like free pistol, I expect the Hammerli pistols to surpass the M41; however, I have no experience with the Hammerli pistols.
