After I got my GSG5 carbine, a good friend who works in a gun-shop on the coast sent me a pair of 15 round mags.
Being the curious sort, I wondered why GSG used the same mag body for both the 15 and 22 round mags.
Last night I decided to see if the 15 round mags could easily become 22 round mags. The short answer: Oh, yeah!
GSG simply installed a block in the bottom of the mag and glued a plate to either side. The plates are only glued to the spacer though and not the sides of the mag.
I took off the floor plate, drilled the spacer in the front half (it's got a bow-tie profile from the bottom), which broke the glue and made removing the plates a "snap". Removing the plates let the spacer fall out the bottom. The spring seems the same as the ones in my 22 round mags, but I stretched them just a bit to be safe.
After the “fix”, they run just fine.
