The 1300 definitely has an extractor if that is what you're asking (part #74 on the Brownell's schematic). Sound like it needs to be checked for proper function. The 1300 (aka "Speed Pump") is generally thought of as a solid and reliable shotgun and the Defender should be up to any SD/HD task. The extractor is the typical "hook" on the left side of the bolt.
