Will an Aftermarket Guide Rod Fit My Pistol?
Beyond Glock, Sig, CZ, and 1911 — NDZ also covers the Springfield Echelon, Ruger RXM, and S&W CSX.
"Will it fit my gun?" — here's the honest answer
A guide rod has to seat exactly in your frame, clear the barrel as it tilts, and carry a spring sized to how far your slide actually travels. Those dimensions change with every model and often every generation, so a rod is not a universal part you shuffle between guns — it's built for one platform's recoil setup. That's why the answer always comes back to your exact model and gen.
Check before you buy
Match your exact model and generation against the table on this page (and the full fitment guide) before you order. If your gun isn't listed, don't force a close-enough part — hit up NDZ.
Other platforms — Echelon, RXM, CSX
NDZ also builds dedicated rods for the Springfield Echelon, Ruger RXM, and S&W CSX. Once fit's confirmed, spring weight is a separate call based on your ammo — see the spring weight guide.

FAQ
- How do I know if an aftermarket guide rod fits my pistol?
A rod is built for one platform's recoil setup, so cross-reference your exact model and generation against the table above or the full fitment guide. NDZ assemblies are made per platform.
- Can I run a rod from a similar-size pistol?
No — even guns that look alike differ in frame seat, barrel geometry, and slide travel, so the rod has to match the specific model. Run the listed part for your platform, not a close-enough one.
- Does NDZ make a guide rod for the Ruger RXM?
Yes — see the Ruger RXM row (NDZ-GRA-RXM-V) in the table above.
- Does NDZ make a guide rod for the S&W CSX?
Yes — see the S&W CSX row (NDZ-SW-CSX-GRO-V) in the table above.
- What if my platform isn't in the table?
Check the fitment guide's other platform pages — NDZ keeps adding to the supported list.
