The Type 97 Shinhoto, yes. The Type 97, no. The original low velocity Type 97 57mm gun was a rather inadequate weapon against armor and was best suited for infantry support. It was not until the Type 1 47mm gun was introduced on the Shinhoto that the platform became an effect anti-armor weapon. Keep in mind that the Stuart was also a more nimble vehicle, with a notably higher power-to-weight ratio, and superior reliability.
