Weight
Weighing 29 ounces unloaded, Ruger’s P345 pistol features an aluminum frame construction that balances durability with practical carry weight.
The polymer grip panels and aluminum alloy frame contribute to the balanced mass ratio between the slide assembly and lower receiver, ensuring consistent sight picture recovery during rapid-fire sequences.
You’ll find the pistol’s weight distribution optimized for enhanced portability while maintaining optimal recoil management.
Barrel Length
Measuring 4.2 inches in length, the P345’s barrel features standard 6-groove rifling with a 1:16 right-hand twist rate. You’ll find the muzzle length precisely machined to ensure optimal lockup with the slide.
The barrel profile incorporates a recessed target crown that protects the rifling and promotes accuracy. The hammer-forged, stainless steel construction delivers consistent shot-to-shot performance.
Material Made Out Of
Nearly all major components of the P345 utilize high-grade stainless steel construction, with the slide and barrel featuring 416 stainless steel for enhanced corrosion resistance.
The frame’s made with glass-filled polymer construction, offering durability while reducing overall weight. The stainless steel components include the slide stop, magazine release, and internal parts. The hammer and sear are precision-machined from bar stock stainless steel.
Chambered In
The Ruger P345 chambers the proven .45 ACP cartridge, complementing its stainless steel construction with substantial stopping power. You’ll find this pistol’s caliber options limited to .45 ACP, focusing on maximizing performance in this specific chambering.
The recoil management system effectively handles the .45 ACP’s substantial muzzle energy, which typically generates around 400 foot-pounds of force at the muzzle.
Capacity
Standard capacity for Ruger’s P345 comes in at 8+1 rounds of .45 ACP, utilizing a single-stack magazine configuration. The magazine capacity allows you to carry eight rounds in the magazine plus one in the chamber.
You’ll find the ammunition capacity sufficient for personal defense, though it’s lower than some double-stack .45 ACP pistols. Factory magazines feature witness holes for round counting.
Trigger Pull
Moving from magazine considerations to firing mechanics, Ruger’s P345 features a double-action/single-action trigger system with measured pull weights of 10-12 pounds in DA mode and 4-5 pounds in SA mode.
You’ll notice the trigger pull consistency remains stable throughout extended firing sessions. The DA/SA transition’s distinct weight difference lets you maintain positive trigger control while adapting to your preferred firing method.
Safety?
While maintaining robust safety features, Ruger’s P345 incorporates multiple mechanical safeguards into its design. You’ll find an ambidextrous manual safety lever, firing pin block, and loaded chamber indicator. Proper trigger discipline remains essential when handling this firearm.
The pistol also includes safe storage recommendations, suggesting the use of a certified gun lock and secure storage container when not in use.
Action
Beyond its safety mechanisms, the P345’s action showcases Ruger’s commitment to reliable engineering. You’ll find a double-action/single-action trigger design with a smooth 10-pound DA pull and a crisp 4.5-pound SA break.
The pistol’s standard magazine capacity is 8+1 rounds of .45 ACP, featuring a metal-reinforced polymer construction. The slide operates on a traditional short-recoil system.
Optic Ready?
Unlike modern striker-fired pistols built with mounting plates, the P345’s slide isn’t optics-ready from the factory. You’ll find limited optic compatibility since the slide lacks pre-drilled mounting points or a standardized footprint for red dots.
If you’re considering aftermarket optics, you’ll need custom gunsmithing work to mill the slide, though this may compromise the pistol’s original finish and warranty coverage.
Review
The P345’s polymer frame offers reliable .45 ACP performance with minimal muzzle flip, though you’ll notice the trigger pull is heavier than comparable striker-fired pistols at 10-12 pounds. You’ll find the ergonomics excel with aggressive grip texturing and a natural point of aim, but the slide-mounted decocker/safety placement can be awkward during rapid manipulations.
The pistol’s proven track record shows consistent 3-4 inch groups at 25 yards with quality ammunition, though some users report occasional failure-to-feed issues with hollow point rounds through the 8-round magazine.
Pros
Despite its discontinued status, Ruger’s P345 delivers exceptional value with its balanced design and reliable .45 ACP performance. You’ll appreciate the ergonomic design with customization options for enhanced control and accuracy.
| Feature | Benefit | Performance |
|---|---|---|
| Polymer Frame | Weight Reduction | 29 oz Unloaded |
| Fixed Barrel | Accuracy | 2″ Groups at 25y |
| Integral Rail | Accessory Mount | MIL-STD-1913 |
| Dovetail Sights | Adjustability | 3-Dot System |
| Steel Slide | Durability | Nitride Finish |
Cons
Several critical limitations affect the P345’s overall performance profile. You’ll find the disassembly procedure difficult, requiring extra steps compared to similar .45 ACP pistols. The recoil management concerns become evident during rapid-fire sequences.

Frequently Asked Questions
Is the Ruger P345 Still in Production Today?
You won’t find the P345 in production today, as Ruger discontinued it in 2009. While this model offered impressive trigger pull quality and maintained accuracy at longer ranges, it’s been replaced by newer designs.
You’ll notice the P345’s legacy lives on through its mechanical innovations, including the cam-block barrel lock-up system and double-action/single-action trigger mechanism. If you’re seeking one, you’ll need to explore the secondary market.
What Holsters Are Compatible With the Ruger P345?
Picture yourself browsing through a display case of holsters at your local gun shop. You’ll find several compatible options for this .45 ACP semi-automatic pistol. Most standard trigger guard holsters designed for full-size .45s will accommodate your firearm, including IWB (Inside Waistband) and OWB (Outside Waistband) variants.
Due to the pistol’s dimensions, pocket holsters aren’t recommended. Look for holsters specifically mentioning P345 compatibility or universal .45 ACP full-size fitment.
Can the P345 Handle +P Ammunition Safely?
You’ll be pleased to know that +P ammunition is safely compatible with your firearm. The reinforced slide and robust recoil spring assembly effectively manage the increased pressures and recoil forces.
While magazine capacity remains unchanged, you’ll notice enhanced muzzle velocity and terminal performance with +P loads. Just remember that sustained use of +P ammunition may accelerate wear on internal components, so it’s wise to alternate with standard pressure rounds for practice.
How Does the P345 Perform in Cold Weather Conditions?
You’ll find that cold weather performance largely depends on proper lubrication and maintenance.
Below freezing, it’s essential to use temperature-resistant lubricants to maintain trigger smoothness and slide function. Magazine reliability can be affected when temps drop, as spring tension may decrease slightly.
Consider using synthetic lubricants rated for sub-zero conditions, and keep your magazines clean and free of moisture to prevent feeding issues in cold environments.
What Is the Average Lifespan of a Ruger P345 Magazine Spring?
“A spring in the hand is worth two in the drawer,” as they say. You’ll find that quality magazine springs typically maintain their durability for 10,000-15,000 compression cycles.
While spring replacement frequency depends on usage patterns and storage conditions, you should expect 5-7 years of reliable service under normal use. Regular inspection for fatigue, deformation, or reduced tension is crucial.
It’s recommended to rotate your magazines and avoid leaving them fully loaded for extended periods.
Conclusion
You’ll find the P345 stands the test of time as a reliable .45 ACP semi-automatic pistol with its 8+1 capacity and polymer frame construction. While discontinued in 2013, its ergonomic grip angle and 4.5-inch barrel deliver consistent shot placement. The dual recoil spring assembly and precision-machined slide rails ensure smooth cycling. When all the chips are down, this striker-fired pistol maintains Ruger’s reputation for durability and accuracy.
