Tikka t1x magazine - Tikka T1X .22LR 10 Rounds Rifle Magazine

This magazine does not hold 10-rounds; it only holds 9-rounds. It is clearly advertised as holding 10; I've read through all the material and there is nothing that indicates it is 9+1, may hold 9 due to a tight spring, or any other reason for holding 9-rounds. I am not the only person on this review who found the same issue. While the it functions well, it is still false advertising to call this a 10-round magazine. Not sure if it is worth getting my money back since this product is directly from Tikka and it does function/feed well (as I would expect it to since it is from Tikka).
