¶ FMDA DD19.2
FMDA's DD19 is a compact Glock Gen3 pistol frame. It is both well proven and like its big brother serves as the base for many other Glock frames.

The DD19.2 is a lot like its bigger brother, the DD17.2. It is easy to print and easy to find parts for. Its smaller size makes it slightly more annoying to assemble but all in all it's not a challenge when printed correctly. The base model allows for either a Gen3 slide lock spring or a Gen5 one. It also comes with a detailed and easily followed instruction manual.
Several remixes are crossover variants, meaning they take the shorter G19 slide bt use the full sized G17 grip.
The DD19.2 has its own set of rails which are meant to be hand-machinable using nothing more than a chunk of aluminum and a dremel. Several manufacturers also offer rails at very reasonable prices.
All combined this makes The DD family an ideal project for a first time builder and the choice between 17 and 19 is really a matter of personal taste (or hand size). A DD19 printed with a glass filled nylon is likely on par with an OEM Glock frame.

¶ Build Notes
The front rail should be snug but should slide in without too much resistance. If it requires a great deal of force or some filing to insert the rail your frame is likely too fat, caused by over-extrusion. If the front rail drops in with no resistance or rattles your frame is likely under-extruded.
An over-extruded frame can be filed down to functional. Removing material from the rear rail slot is nearly impossible though, and that makes pinning the rear rail cleanly near impossible. Fortunately the rear rails do not have to be exact--drilling a new hole or pinning them slightly high is an option (which might require more filing due to the slide being angled)
Non-OEM parts are not always to spec and may cause issues. If using cheap parts it's a good idea to work the slide with a lot of oil a couple hundred times to loosen the parts up.
¶ Parts Availability
Glock parts as a whole are widely available due in no small part to the 80% market. Cheap 9mm parts kits in particular are offered by many retailers. Locking blocks often have to be bought separately but they too are easily found.
Rails for the FMDA are the only non-standard part and even those are easily acquired. As it is the most common rail system in the 3d printed market several reputable vendors offer them.
¶ Derivatives
Almost all Glock frame derivatives are derived from one of the FMDA releases and a complete listing would be both time consuming and noisy. Here are some of the more notable variants and variant creators:
- Booligan Custom Gunworks (several variants on odysee profile)
- G1911 (modeled to look and feel a little more like a 1911)
- Lil' Chungus (under-barrel weights)
- CAG19 (G19 carbine designed to be California legal)
- ChairmanWon's stippled glocks (custom stipplings, 19 and 19x)
- Digital Nimbus Labs (several variants on odysee profile)
- DNL DD19.2 (gen3 and gen4 frame, beaver tail, 19 and 19x, optional stipple and pic rail)
- Doot Defense DD19.2 19x Wombat Master (stipple, beaver tail, magwell, double undercut, 19x only)
- RD19.2 (pic rail, designed for printing rails down)
