The long boy 10mm Glock but in ModulGlock format.
Has two different slides, barrels and frames. Mostly basing it on the Glock 17L options here.
The slide stop won't match when you use standard ModulGlock due to mismatch on how size of its frame/slide but may get fixed in the future.
The frames will change its chambering to use 10mm Auto rounds/magazine. Otherwise, there is also a "prebuilt" version with a more proper finish.
