  A: The box includes the shotgun, a Derya bag with user manual and WTTA flyer, basic cleaning/polishing cloth, tool, and choke set (F, M, C).
• Q: Why is the steel receiver better?
  A: The mono-block steel receiver provides superior strength and durability, offering excellent resistance to wear and recoil while ensuring long-lasting, reliable performance.
• Q: What is the minimum recommended shell length or type for reliable function in the EX1400?
  A: Users can use mini shells with the EX1400 as long as shell length does not exceed the chamber length specified on the shotgun. Choose ammo according to C.I.P and SAAMI specifications. Rarely, cheaper ammo brands may swell and get stuck.
• Q: What is the recommended break-in period for the EX1400, including the number of shells needed?
  A: There is no break-in period for side-by-side shotguns. Users can use it after cleaning and lubricating. However, the top lever is designed to sit perfectly after 500-1000 shots (no effect on shooting). Over time, the locking system and ejectors will stabilize.
• Q: What are common causes of failures to fire or eject in the EX1400, and what fixes are recommended?
  A: Some shells may get stuck due to expansion in the chamber. Recommend choosing ammo according to the chamber length and width (chamber length is written on the shotgun). For extraction issues, use alternative tools that won’t damage the extractors and chamber. If the shell does not fit, check ammo sizes and look for alternatives.
• Q: Which specific shell brands or types have been known to cause issues in the EX1400, and what alternatives do you recommend?
  A: Rarely, some cheaper ammo brands may swell and get stuck. Recommend considering C.I.P and SAAMI specifications when buying ammo.
• Q: What is the shelf life of the EX1400 when stored properly, and how long can it remain functional without use?
  A: It may remain functional for 10+ years if kept away from elements such as corrosion or heat. However, springs under tension may need service due to wear.
• Q: In durability tests, how many shells has the EX1400 survived without failure?
  A: The EX1400 model has successfully completed 10,000 rounds of performance testing with 28 g cartridges without any failures.
• Q: Does adjusting the triggers affect the EX1400's reliability?
  A: Our shotguns have a trigger group patented by Parantez R&D Defense. Recommend contacting us through authorized distributors for service/replacement or adjustment of any kind.
• Q: What challenges might left-handed users face with the EX1400, and are there options for left-handed controls?
  A: The EX1400 model is optimal for ambidextrous use. Left-handed people won’t face any challenges regarding operation.
• Q: What are the recommended cleaning and lubrication procedures for the EX1400?
  A: Clean and lubricate the ejector, receiver hinge, and external hammers with proper lubricants after use. Clean the barrel with proper tools. Avoid using corrosive or water-based cleaners or lubricants not designed for firearm use.
• Q: How should users troubleshoot misfires or stuck shells in the EX1400 barrels
  A: First, read and understand the user manual for safety and situations like hang fire or misfire. If all safety precautions are taken (safety on, no live ammo in the chamber, safe direction), extract the spent shell or stuck projectile using proper tools and techniques. If the problem persists, have the firing pins and hammers checked by a qualified gunsmith.
