Just remember it is a bit of a glass cannon, when it comes to incoming German rounds. The open topped turret was another design deficiency, allowing for that one lucky grenade toss to ruin the crew's day. An unfortunate trait that all fully tracked US tank destroyers shared. Not nearly as fast as the M18 Hellcat it did have thicker armor overall.
In spite of any deficiencies, the M10 was produced in significant numbers, 4,993 by GM from September 1942 to December 1943. The British were supplied 1,654 M10's, with more than a thousand converted to use the British 17-pdr. gun.
