High-Capacity 25-Round Magazine for Ruger SR .40 Pistols
This ProMag magazine is purpose-built for Ruger SR-series .40 S&W pistols, giving you:
25-round capacity in .40 S&W
Extended mag body for more shooting, fewer reloads
A great option for range work, drills, and competition-style practice
Instead of constantly stopping to reload factory-standard mags, you can focus on your shooting—running longer strings, working on transitions, and getting more done each trip to the range.
Built from Blued Steel – Strong, Rigid, and Reliable
The RUGA38 uses a blued steel magazine body, offering:
Excellent strength and rigidity, especially under full 25-round loads
Durable blued finish that helps resist corrosion and wear
A classic look that pairs nicely with both factory and custom Ruger SR pistols
Steel mags are favored by many shooters for their longevity and solid feel, and this ProMag is built with that in mind.
Designed for Smooth Feeding and Consistent Function
ProMag designs its extended magazines to deliver reliable performance when paired with quality ammunition and a well-maintained pistol. The 25-round RUGA38 typically features:
A precision-formed steel body to maintain proper geometry and stack angle
A reliable spring and follower system built to keep rounds feeding smoothly
A reinforced feed lip area to help maintain shape and consistent presentation of cartridges
For best results, pair this magazine with good .40 S&W ammo and clean your pistol and mags periodically—especially if you train hard or run classes.
Extended Design – More Grip and Control
The extended body of this 25rd .40 S&W magazine also offers some ergonomic benefits:
Provides extra length for a more secure support-hand index on the mag in reloads
Gives larger-handed shooters more to grasp when seating or stripping the magazine
Makes mag changes easier under stress thanks to the added surface area
It’s a practical design choice for dynamic training, competition-style shooting, or anyone who wants more control during reloads.
Ideal for Range Days, Training, and Practice
While capacity laws vary by location (always check your local regulations), in appropriate areas this 25-round Ruger SR .40 S&W magazine shines in:
Range practice – Run longer drills without constantly topping off magazines.
Training classes – Spend more time shooting and less time stuffing ammo.
Competition-style drills – Practice transitions, reloads, and movement with real-world extended capacity.
Defensive skills development – Work on realistic strings of fire with more rounds on tap.
It’s not just about more bullets—it’s about more uninterrupted time to work on fundamentals and advanced skills.
Great Backup or Spare Magazine
It’s always smart to have extra magazines on hand, and the ProMag RUGA38 is an excellent addition to your kit:
Keep one loaded and ready as a backup mag for range sessions.
Use it as a designated training mag, while keeping factory mags for carry (where applicable).
Rotate it in with other mags to evenly distribute wear.
If you own a Ruger SR-series .40 pistol and want a dedicated high-cap magazine, this one fits the bill.
Easy to Maintain and Store
Like most quality steel magazines, the ProMag 25rd RUGA38 is straightforward to care for:
Wipe down the blued steel body after use to remove sweat, moisture, and carbon.
Occasionally disassemble (if desired) to clean the spring and follower.
Store unloaded or partially loaded depending on your preference and usage patterns.
Regular maintenance will help ensure long-term reliability and consistent feeding for thousands of rounds.
