Where to buy a 5 or 10 rd HK G3 magazine

[ShootAndHunt]

My PTR91 is very accurate and now I am using it as my "precision shooting rifle". The only problem annoying me is that it comes with a 20 rd magazine, which is too long and makes it uncomfortable and inconvenient in prone or bench shootings, so I want to buy a 5 or 10 rd HK G3 magazine. However, I cannot find a quality one in my local store or on the internet? Could anyone in the know give me some online place carrying them?

Thanks in advance!
