Works for original purpose but has misleading description. - Glock MF10017 Magazine G17/34 9mm 10 Round Black Finish Packaged

It works perfectly fine if you live in a magazine capacity restrictive state. However, the Product Information states, and I quote, "Compact and subcompact Glock pistol model magazines can be loaded with a convincing number of rounds - i.e. Glock 26: up to 33 rounds.". Unfortunately, this can be understood as I can change the baseplate (in a non-restrictive state) and achieve extended capacity. However, this is not possible. The internals of the magazine (metal lining) does not allow for a new spring to be introduced and is restricted to about half the normal internal spacing. If I could attach a picture I would. Overall, works for the intended purpose but does not allow for any modifications. I checked for normal Glock 17 mags at the time but none are available here and I was foolishly tempted into this venture.
