The Mauser Model 98 had all of the improvements since the Mauser 88 Commission Rifle. And the first thing was to be not dependent on a separate clip to fire the gun from the magazine.
Then there were 93s, 95, 96s and 98s. I don't know what would have happened to the 94s and 97s. Maybe they were so bad they were never made in any production numbers.
The military Mausers had a lot of slop that didn't hurt anything because they were tight "enough" when they were in battery. But I had a famous dean of the gunmakers tell me you should never let a Mauser go out "sloppy" but should tighten it up. He told me how to do that, but I haven't been brave enough to try it "yet". I'll have to try that when I get time.
The nicest Mausers were the commercial FNs, especially those on the Southgate Weatherbys.
