TR-1Upgrade – Performance Born on the Field
Hard work pays off, and our sporting experience has guided us in the development of products that genuinely enhance the performance of handguns. To win a competition, the perfect harmony between the shooter and the firearm is essential.
The shooter, driven by passion, must combine technical expertise and mastery of the weapon with safe and effective use. The ability to handle malfunctions can make the difference between success and failure – in competitions, as in real life for those who operate daily in the field.
The weapon, in turn, can be optimized with targeted upgrades that enhance its performance. Only by achieving this synergy can the maximum result be obtained.
Each of our products is designed to provide a tangible advantage: time savings, greater efficiency, and better control. Performance is born from the balance between the shooter’s skill and the quality of the equipment – whether it’s a superior trigger system, an optimized grip, or other strategic accessories.
TR-1Upgrade is born from direct experience on shooting ranges, bridging defense and sport. It grows every day, thanks to interactions with those who truly love this world, turning passion and necessity into innovation.
TR-1upgrade® follows proper design principles, as this is an essential requirement for the good quality of the product to be created.
The type of design can be "innovative" and/or "adaptive":
Development of a new product through the adaptation and revision of an already existing item, improving it and providing both an aesthetic and mechanical "upgrade," and/or through the complete creation of a new accessory following well-defined principles.
All of this is thanks to the decade-long experience gained in the field and the developments carried out in parallel with the best sport shooting Testimonial recognized nationally and internationally.
The opposite or reverse operation to design is, therefore, the analysis of the characteristics/performance of an already manufactured product to verify its compliance with the design specifications and quality standards.
If these specifications are not met, the process iterates back to the logical-functional design phase, taking into account the missing requirements or specifications.
The most requested material is certainly aerospace aluminum, which characterizes most of the products created. Lightness and strength are the two fundamental elements that define the raw material, assisting in its technical and mechanical functions.
The actual manufacturing phase is followed by the testing phase of the proposed project, often going through an experimental prototype stage or pilot installation.
Once this stage is passed, the product is then manufactured, followed by the final testing phase of the completed work.
