In a medium bowl, gently stir together tomato, peaches, ketchup, chili sauce, onion, lime juice, ¼ teaspoon salt, horseradish, red pepper, and cilantro. Refrigerate while preparing shrimp.
In a large cast-iron skillet, heat oil over medium-high heat. Sprinkle shrimp with remaining 2 teaspoons salt and black pepper. Cook shrimp in batches until shrimp begin to curl and turn pink, about 2 minutes per side.
To serve, spoon tomato mixture evenly into 4 serving dishes. Arrange shrimp around edge of each dish. Garnish with cilantro, peaches, and tomatoes, if desired. Serve immediately.
