Decrease your trigger pull weight and achieve more of a positive reset via tuning while keeping 100% ignition reliability.


Armory Craft P365 Ultimate Master Spring Tuning Kit is the best value tuning kit on the market and includes the following FOUR springs:

  • Reduced Weight Striker Spring (-20%)
  • Reduced Weight Striker Block Spring (-25%)
  • Reduced Weight Sear Spring (-25%)
  • Positive Reset Trigger Return / Trigger Bar Spring (+10%)


Like other aftermarket companies, the Armory Craft 365 spring kit comes with the popular 3 springs that reduce the trigger pull weight, however unlike the competition the Armory Craft P365 spring kit also includes a "Positive Reset Spring". (which can also be purchased separately from the above drop-down menu).


  • P365 pistols have somewhat of a "mushy" feeling reset. This spring helps in mitigating that feeling.
  • Perceived take-up resistance increased by less than 0.5 lb, however the trigger break resistance remains the same.
  • Considerably improved tactile and audible reset


We also offer this very popular "Positive Reset Spring" for all P320 pistols as well. Please CLICK HERE.


We also sell spring tuning kits for the classic P-Series pistols (P220, P226, P229 etc).  Please CLICK HERE.


*Discount pricing is available for gunsmiths and dealers with volume purchases. Please contact us at for more details.


All triggers, hammers, springs or any other ignition gun parts are intended for installation only by a gunsmith or a qualified armorer.
