I bought a Viking Holster off Ebay the other day for my Firestorm .380. It is said that Walther PPK holsters will work for my Firestorm. So I bought this holster, a shoulder holster off ebay that's for a walther. I got it today and the retention strap is about half an inch short. I like the holster, it's a good looking leather shoulder holster and I got it for 40.00 which I thought was a good price (I hope it was) but this one strap is too short. Anyone have any ideas? Are there places online to buy such things? Any help is appreciated. Thanks.
