Hi, I'm very sorry if this is in the wrong spot but it was the best fit I could find!
I went to a gun show yesterday and they had a pink/black Walther P22 (picture below)
I asked the vendor if he had one in a larger caliber. He said they do make a larger caliber, but he didn't have any.
I have not been able to find a larger caliber than the 22 in online searches. Does anyone have any tips?
