Enlarged bolt handles, safeties, and bolt releases used to be aftermarket accessories. Increasingly, they are standard equipment on semi-autos intended for waterfowl. Enlarged loading ports, inspired by three-gun competition and its need for speed, are finding their way onto waterfowl guns too. All these features make a gun easier to handle in the cold. As one who suffers from numb, weak fingers on late-season hunts, I like a gun with a fairly soft magazine spring as well, so long as it doesn’t impair the gun’s function.
