Reason I ask this question is a "friend of mine" has found a Mauser that is chambered for this round, he likes the look and feel of the gun but I am not familiar with this caliber. It is used and said to have been shot "only three times" and it has me wondering if the ammo availability was the cause of this. Is this ammo hard to find? Is it more expensive than regular 9x18? Is there a round known as 9x18 ultra police and if so, is it the same thing?
