Glock:
12 - 17 round
4 - 33 round
2 - 10 round (factory ones for my G26)
HK:
4 - 12 round
2 - 10 round
AK:
2 - 30 round, but I still have not finished building my rifle, so they are useless anyway.
AR-15:
Not sure, around 12-14 functioning. Buying several more PMags this week
10/22:
10 - 25 round
1 - 30 round Eagle, when it decides to work.
The only other higher than 10 capacity pistol or rifle I own is my wife's Taurus, and I am trying to get her to sell it and buy a Glock so we both can use the same magazines.
Depending on how much money I can come up with to spare on them, I will probably try and stock up on a lot of high capacity magazines when the next gun show comes around in November. The problem is it will be after the election, so a lot of the dealers will probably already be increasing the prices. That is why I am going to go ahead and get some AR-15 magazines this week.
In relation to this, I have also been looking at purchasing quite a few rebuild kits for my existing magazines. If they do reinstate the AWB, I fully expect it to be a permanent ban this time instead of a 10 year deal.
