The Essential Ruger Mark II & 22/45 10-Round Blued Detachable Magazine (Part #90045)

For enthusiasts, competitors, and new shooters alike, the Ruger Mark series of .22 LR pistols represents an iconic staple in the world of firearms. Renowned for their accuracy, reliability, and comfortable ergonomics, models like the Mark II and 22/45 have become go-to choices for everything from casual plinking at the range to serious target practice and even competitive shooting. At the heart of this consistent performance lies a critical component: the magazine. Specifically, the Ruger 90045 Mark II / 22/45 10-Round Blued Detachable Magazine is an indispensable accessory designed to ensure your shooting experience is as smooth and uninterrupted as possible.

Why is the Right Magazine So Important for Your Ruger Mark II or 22/45?

Many new firearm owners often underestimate the crucial role a high-quality magazine plays in overall pistol function. A firearm is only as reliable as its feeding mechanism. A faulty or poorly constructed magazine can lead to an array of common malfunctions, including failures to feed, failures to eject, and misfires, turning an enjoyable day at the range into a frustrating troubleshooting session. This is particularly true for .22 LR firearms, which can sometimes be more sensitive to ammunition and feeding issues due to the rimmed cartridge design.

For Ruger Mark II and 22/45 owners, the Ruger factory original magazine, part number 90045, provides the peace of mind that comes with guaranteed compatibility and Ruger's rigorous quality control. This magazine is engineered precisely to the specifications of your pistol, ensuring a perfect fit, consistent spring tension, and reliable cartridge presentation. Whether you’re a seasoned shooter looking to maintain peak performance or a beginner seeking a hassle-free introduction to the shooting sports, investing in authentic Ruger magazines is a fundamental step toward maximizing your pistol’s potential.

Unpacking the Features of the Ruger 90045 Magazine

The Ruger 90045 magazine is a testament to functional design and durable construction. Here’s a closer look at its key attributes:

• 10-Round Capacity: This standard capacity is ideal for a variety of shooting activities. It strikes an excellent balance between providing ample rounds for sustained shooting and maintaining a compact profile for easy handling and storage. For target practice, it means fewer interruptions for reloading, allowing you to focus more on your fundamentals.
• Caliber: .22 LR: Specifically designed for the venerable .22 Long Rifle cartridge, this magazine ensures proper feeding of one of the most popular and cost-effective ammunition types available. The .22 LR is perfect for training, plinking, and general sport shooting due to its low recoil and affordability.
• Blued Finish: The magazine features a classic blued finish, which provides a layer of corrosion resistance and matches the aesthetic of many Ruger Mark II and 22/45 pistols. This durable finish helps protect the steel body from wear and environmental elements, contributing to a longer service life.
• Steel Construction: Crafted from robust steel, the Ruger 90045 magazine is built to withstand repeated use and the demands of frequent loading and unloading. Steel magazines are known for their strength and resistance to deformation, which is crucial for maintaining consistent feeding geometry over time.
• Detachable Design: As a detachable box magazine, it allows for quick and easy reloads, which is essential for both competitive shooting and efficient range sessions. Its design facilitates simple insertion and removal from the pistol grip.

Who is This Magazine For? Addressing Common Shooting Scenarios

The Ruger 90045 magazine is a must-have for virtually every Ruger Mark II and 22/45 owner. Consider these common questions and use cases where this magazine excels:

"I want to spend more time shooting and less time reloading at the range. What's the best approach?"

Having multiple spare magazines, such as the Ruger 90045, is the most effective solution. With several loaded magazines ready to go, you can significantly increase your active shooting time and reduce downtime spent at the bench refilling a single magazine. This is especially valuable for focused practice sessions.

"How can I improve my pistol training and marksmanship skills?"

Efficient practice requires consistency. With several magazines, you can practice tactical reloads, transitions, and other drills without interruption. This helps build muscle memory and improves your overall proficiency with your Ruger Mark series pistol.

"My older Ruger Mark II magazine isn't feeding reliably anymore. What should I do?"

Magazines are wear items, and over time, springs can weaken, and feed lips can deform. Replacing old, unreliable magazines with a new, factory-spec Ruger 90045 can instantly resolve feeding issues and restore your pistol's dependable performance. This is often the first and most cost-effective troubleshooting step.

"I'm participating in a local shooting competition. What accessories do I need?"

While rules vary, many competitions benefit from having multiple magazines. The 10-round capacity is generally compliant for most informal and formal shooting events. Having spare magazines ensures you’re prepared for multiple strings of fire or in case of a malfunction during a stage.

"I just bought a Ruger 22/45. What are the essential accessories to get?"

Beyond ammunition, a couple of extra magazines are universally recommended. They enhance your shooting experience from day one, providing flexibility whether you're plinking in the backyard (where legal) or attending a formal training class.

Maintaining Your .22 LR Magazines for Longevity and Reliability

Proper maintenance of your Ruger 90045 magazine is crucial for ensuring its long-term reliability. Unlike centerfire pistol magazines, .22 LR magazines can be particularly susceptible to fouling from unburnt powder and lead residue due to the nature of rimfire ammunition.

Here are essential tips for caring for your magazines:

• Regular Cleaning: Disassemble your magazines periodically (refer to your pistol's manual or a reliable guide for safe disassembly) and clean all internal components. Use a soft brush, patches, and a gun-safe solvent to remove carbon buildup, lead shavings, and dirt from the follower, spring, and inside of the magazine body. Ensure all grit is removed, especially from the feed lips and the follower channel.
• Avoid Over-Lubrication: Generally, .22 LR magazines function best when relatively dry inside. Excessive lubrication can attract and trap powder residue and grit, leading to sluggish follower movement or malfunctions. A very light, almost dry lubricant on the spring or follower after cleaning might be acceptable, but often it's best to leave them dry.
• Inspect for Wear and Damage: Regularly check the feed lips for any signs of bending, cracks, or excessive wear. Inspect the magazine body for dents or deformities that could hinder the follower's movement or cartridge stack. Check the spring for kinks, rust, or weak spots.
• Proper Storage: Store magazines unloaded if possible, especially for long periods, to prevent spring fatigue. Keep them in a clean, dry environment to prevent rust and corrosion.

By adhering to these simple maintenance practices, your Ruger 90045 magazines will serve you reliably for years to come, consistently delivering the performance you expect from your Ruger Mark II or 22/45 pistol.

The Ruger Difference: Quality and Trust

When it comes to firearm accessories, the choice between original equipment manufacturer (OEM) parts and aftermarket alternatives can be significant. For critical components like magazines, opting for an OEM product like the Ruger 90045 provides unparalleled assurance. Ruger, a leading American firearm manufacturer, stands behind its products with a commitment to quality, safety, and performance.

Purchasing a genuine Ruger 90045 magazine means you are acquiring a product that has been:

• Designed by the original engineers: Ensuring perfect compatibility and optimal performance with your Ruger Mark II or 22/45 pistol.
• Manufactured to strict quality standards: With precise tolerances and durable materials that aftermarket alternatives might not consistently match.
• Tested rigorously: To meet Ruger’s high standards for reliability and longevity, giving you confidence in every shot.

This dedication to excellence is why Ruger firearms and their components are trusted by countless shooters worldwide. Choosing the Ruger 90045 is not just buying a magazine; it's investing in the continued reliability and enjoyment of your Ruger pistol.
