Gen3.5 Glock G19 and G26XX frames with gen 5 magazine release. (DD19.2 and DD26.2 rails)

These are frames in which the right-hand only gen-3 magazine releases have been replaced with the reversible gen-4/5 one: 1) Remix of the FMDA DD19.2 2) PP19O- a G19 sized adaptation of my ergonomic PP43XO design.

(26XX = G26 slide + G17 grip) [https://odysee.com/@BrokenBullets:9/V2-The-Final-Strike:a] 4) FMDA DD26.2XX, the bastard child of the FMDA DD26.2 and DD17.2 5) an extended gen5 mag release .step files included
