Elevating Your Aim: Sights for the P320
Stock Sights Overview
The sights on any handgun are fundamental to accurate shooting. They guide your eye and help you align your weapon with the target. The P320, out of the box, typically comes equipped with factory sights that, while functional, often leave room for improvement. Upgrading your sights is frequently one of the first and most impactful modifications you can make.
The standard sights often present limitations, particularly in low-light conditions or during rapid target acquisition. They might lack the visibility needed for quick follow-up shots or the precision needed for accurate long-range engagements. Fortunately, the aftermarket world is teeming with options to address these shortcomings.
Aftermarket Sight Options
Iron Sights
Tritium Night Sights
Consider, for example, the benefits of tritium night sights. These sights use tritium vials that glow in the dark, providing a readily visible aiming point in low-light environments. This feature is invaluable for self-defense scenarios or when you find yourself shooting at dusk or dawn. Leading manufacturers like Trijicon and Ameriglo offer a variety of tritium sights specifically designed for the P320, ensuring a clear and reliable sight picture when it matters most.
Fiber Optic Sights
Fiber optic sights represent another popular upgrade. They utilize fiber optic rods to gather ambient light, creating a bright and easy-to-see aiming point. Fiber optic sights excel in daylight conditions, making target acquisition incredibly fast. This is especially beneficial for competition shooting or any scenario where quick target engagement is crucial.
Adjustable Sights
For those seeking even greater precision, adjustable sights provide the ability to fine-tune your point of impact. This adjustability allows you to compensate for bullet drop or wind drift, optimizing your accuracy over varying distances.
Red Dot Sights (RDS)
Overview of RDS
The increasing prevalence of red dot sights has revolutionized pistol shooting. These sights project a illuminated reticle onto a lens, providing a clear and unobstructed sight picture. The advantages of a red dot sight are numerous, including enhanced target acquisition, improved accuracy, and easier target transitions.
Mounting Options
Mounting a red dot on a P320 typically involves either utilizing the existing slide cut, if available, or using an aftermarket slide that is pre-cut for a specific optic. Another alternative is the use of adapter plates. These plates allow you to mount a red dot sight to a slide that doesn’t have a dedicated optic cut.
Popular RDS Models
When choosing a red dot sight, there are several factors to consider. Battery life is a key consideration; a longer-lasting battery will minimize the need for frequent replacements. The reticle size, which refers to the size of the dot projected onto the lens, is another crucial factor. A smaller dot may provide greater precision, while a larger dot can facilitate faster target acquisition. Durability is paramount, ensuring your sight can withstand the rigors of use and recoil. Finally, consider the overall size and weight of the sight to ensure it complements your pistol’s handling characteristics. Popular choices like the Trijicon RMR, SIG Sauer ROMEO series, and Holosun optics have become mainstays in the P320 upgrade community.
Enhancing Performance: Upgrading the Trigger
Stock Trigger Overview
The trigger is the interface between you and your firearm. Its feel, pull weight, and reset directly impact your shooting performance. The stock trigger on a P320, while generally functional, can sometimes feel gritty or have a long reset, potentially hindering rapid follow-up shots.
Aftermarket Trigger Options
Trigger Kits/Assemblies
Improved Trigger Pull
Upgrading the trigger is a common and highly effective modification for those seeking to improve their shooting experience. Aftermarket triggers can offer significant improvements in several areas. They can refine the trigger pull weight, making it lighter and smoother. They often reduce the trigger travel distance, the distance the trigger moves before firing the gun, which can speed up follow-up shots. A shorter reset, the distance the trigger needs to move forward after firing before it’s ready for the next shot, also enhances the speed at which you can engage multiple targets.
Trigger Bar/Sear Upgrades
Trigger kits are available that replace the entire trigger assembly, offering a comprehensive upgrade. Other options focus on upgrading specific components, such as the trigger bar or sear, the parts that control the firing mechanism.
Several companies specialize in crafting top-tier triggers for the P320. Apex Tactical and Grayguns are two of the most respected names in the industry, known for producing triggers that are both reliable and exceptionally smooth. By investing in a quality trigger upgrade, you can transform the feel of your P320 and potentially see a noticeable improvement in your accuracy and shooting speed.
Fine-Tuning Accuracy and Handling: Slides and Their Modifications
Stock Slide Overview
The slide is the upper portion of the firearm that houses the barrel, bolt, and firing mechanism. A quality slide can significantly enhance both the appearance and performance of your P320.
Aftermarket Slide Options
Features and Benefits
Porting
Aftermarket slide options provide opportunities for a wide range of enhancements. Porting involves cutting openings in the slide and barrel to redirect gases upon firing. This can reduce muzzle rise and recoil, allowing for faster follow-up shots and improved control.
Serrations
Enhancing the slide’s external features is also a popular option. Adding aggressive serrations, the textured grooves on the slide, makes it easier to manipulate the slide, especially with wet hands or gloves. Various finish options, such as Cerakote or DLC (Diamond-Like Carbon), offer increased durability, corrosion resistance, and a unique aesthetic appeal.
Optic Cuts
For shooters looking to mount a red dot sight, an aftermarket slide pre-cut for optics is often the easiest and most effective solution. These slides come with the necessary mounting cuts, eliminating the need for modifications to the original slide.
Popular Slide Brands and Models
Several manufacturers offer exceptional slide options for the P320. ZEV Technologies, Agency Arms, and Grey Ghost Precision are well-regarded brands that provide high-quality slides with various features and finishes to suit different preferences.
Customizing the Feel: Frames, Grips, and Enhanced Ergonomics
Stock Frame Overview
The frame, or grip module, is the lower part of the P320 that houses the fire control unit. Modularity is a cornerstone of the P320’s appeal, and the ability to swap grip modules is one of its most significant advantages. Different frame sizes, materials, and features are available, allowing you to tailor the pistol’s ergonomics to your hand size and shooting style.
