FMDA G26 frame with Gen5 recoil spring cut — will a Gen5 slide work?
FMDA G26 frame with Gen5 recoil spring cut — will a Gen5 slide work?

I recently recovered an old STL of an FMDA-style G26 frame (looks like DD26.2), and I noticed that the front recoil spring cut looks like it was designed for a Gen5 guide rod — it’s deeper and larger than the typical Gen3 spec.
The rest of the frame looks like a Gen3-based FMDA design, though I’m not sure if any internal dimensions were modified for Gen5 compatibility.
Has anyone successfully run a Gen5 G26 slide on one of these? If so, were there any fitment issues with the rails, slide stop cuts, or anything else I should watch out for?
Appreciate any insights or photos if you've done a similar build. 🙏
