I have tried fitting the Kimber mags to my Ciner kit. But havent shot any. It does fit and locks into place.
afa the 17/22 mags, im not sure about if they are the same or not.
just an fyi, you can get 10+ round mags from ciner now.
also, fwiw, the GSG1911, i would do a "wait n see" since its new and chances are some issues maybe there. of couse you could aways be one of the testers to find out.
Kimber mags function fine in the Ciener conversion. I have a Kimber conversion and my BIL has the Ciener. We tried one of my Kimber mags and it fed flawlessly. He must have put 200 shots through it using the Kimber mag.
FWIW, I remember reading that Ciener used to make them for Kimber. Supposedly they started making their own and didn't change much.
Also, a member of another forum I spoke to told me he was able to fit more than ten rounds in the Kimber mags by trimming the follower and spring guide. I haven't tried that yet.
