Description
The factory P320 magazine release sits pretty flush to the frame, and that's a problem if you want faster reloads or a better reach during training. The Strike Industries Modular Magazine Release changes the game by giving you switchable extensions that work with your grip instead of against it. You get two button sizes in the box, so you can dial in exactly what works for your hand and shooting style.
What makes this different from other extended releases is the modular design itself. Instead of being locked into one extension size, you can swap between the standard and extended button by removing a single set screw. This takes maybe 30 seconds and requires nothing more than unloading the gun. That means you can run the tight config when you're carrying in a restrictive holster, then switch to the extended version for competition or range days without any gunsmithing.
Strike Industries Construction and Materials
Build quality matters for parts you interact with constantly, and this release is solid. The main body is stainless steel with a QPQ black coating that resists corrosion and wear. QPQ is an industrial hardening process that penetrates into the metal rather than just sitting on the surface, so it holds up to repeated use and isn't going to flake off. The whole thing weighs barely anything, so adding it to your P320 doesn't throw off the balance or add complexity.
Modular Magazine Release Installation
Installation is genuinely straightforward. The release uses a simple set screw and installs as a drop-in component with no frame modification. Just make sure to use thread locker on that screw during install and you're done. The unit will work with standard P320 grip modules, though compatibility doesn't extend to P320 X-Series frames, M17/M18 military variants, Nitron finishes, or .45 ACP models.

Frequently Asked Questions
Can you switch between the standard and extended button on the Strike Industries magazine release?
Yes, that's the whole point of the modular design. You remove one set screw and swap the button configuration. It takes about 30 seconds and requires no disassembly of the gun. This lets you run tight for carry and switch to extended for range or competition training.
Will this modular release work on my P320 X-Series frame?
No, this release is not compatible with P320 X-Series frames, M17/M18 military models, Nitron finishes, or .45 ACP variants. It works with standard P320 grip modules and is designed for 9mm platforms. Check the Strike Industries website or contact them if you're unsure about your specific frame.
What's the advantage of stainless steel with QPQ finish compared to other coatings?
QPQ is an industrial hardening process that chemically bonds into the stainless steel rather than sitting on top like traditional paint. It resists wear, corrosion, and discoloration better than most coatings. You'll see this finish on high-end tools and duty weapons because it holds up to heavy use without flaking or wearing thin in spots.
Do I need any special tools or gunsmithing to install this?
No, it's a drop-in replacement that uses a simple set screw. You just need to make sure to apply thread locker to that screw during installation. Beyond that, there's no fitting required and no frame modification needed.
