Though ranked as the most sought after carry gun for body guards, ever made;
the Combat master has the classic "limp wristing"/stove piping complaint from many shooters who aren't formerly 1911 affecienados[sp?].
Being so much shorter in the grip frame it is even easier to "limp wrist" these models sometimes so much that the ejected shell doesn't even make it into the "stovepipe" configuration.
Stay away from classicly downloaded reloads,
keep your wrist straight and don't use "magsafe" ammo(too much exposed case for these pistols)
That's all I've ever heard of.
HTH,
