The MODULUS Extended Conversion Kit is built for shooters who want the advantages of a full-size platform without buying a completely different pistol. This kit includes everything you need to convert a Compact Modulus into the Extended configuration in about 90 seconds with just three screws.
What comes in the Extended Conversion Kit
The kit includes an 8-inch slide assembly, extended dust cover, and extended magwell. The dust cover features 6 Picatinny rail sections for mounting lights, lasers, or other tactical accessories. The extended magwell accommodates 17+ round magazines and is purpose-built for the extended platform, balancing reach and controllability.
Why the Extended Configuration Matters
The longer sight radius of the 8-inch slide naturally improves accuracy by giving you a longer sight line, which is especially noticeable in precision work and competition shooting. The extended dust cover provides more rail space if you run mounted optics or accessories. Compared to the Compact or Duty versions, the Extended gives you a full-size feel while maintaining the core MODULUS modularity that lets you switch configurations on the fly.
Designed for Real Versatility
One of the standout features of the MODULUS system is that you don't have to choose between configurations permanently. The Extended conversion kit works with your existing Compact Modulus frame and lower receiver. The slide and dust cover are machined from quality materials and come ready to run. Slides are pre-drilled for direct optic cuts and ship with a cover plate installed, and ZRODelta offers adapter plates for all the common pistol red dots. If you run iron sights instead, the slides come with black steel sights and cocking serrations front and rear.
You can upgrade your existing Compact Modulus using this kit. The Extended conversion includes the slide assembly, dust cover, and magwell that work with your current frame and lower receiver. Installation takes about 90 seconds with just three screws, so you're essentially building a new pistol configuration from parts you already have.
The extended 8-inch slide gives you a longer sight radius, which naturally improves accuracy and makes sight alignment easier, especially for precision shooting and competition. It also feels like a full-size platform while keeping the modularity of the MODULUS system, so you can swap between Compact, Duty, and Extended configurations depending on your mission that day.
Yes, the Extended slide is machined to accept a red dot optic and ships with a cover plate already installed. ZRODelta offers adapter plates for most popular pistol optics like RMR patterns and others. If you prefer iron sights, the slide comes with black steel sights already.
The extended magwell is designed for 17+ round magazines and changes both the height and flare of the pistol. It's purpose-built to work with the extended slide and dust cover as a matched set for the best ergonomics and function in this configuration.
