Probably, leather is forgiving but it would be best to contact the maker. There are minor differences between a P2000sk and P30sk. The molds are different. You could try placing a heavy ZIPLOCK bag around the pistol and insert it into the holster for a day or two. That helps the leather to conform to the pistol.
I found that a Kydex holster for a P2000sk would accept a P30sk, but in doing so it left light scrapes on the inside that made the P2000sk looser. It lost its versatility to use for both platforms. With Kydex you can warm the polymer and re-mold it slightly to fit whatever you want to put into it. As I said, leather is forgiving but it may cause adverse wear on your P30sk.
I carry my V1 P30sk nearly everyday in a MS VM2 made for a P2000sk. Works great - very secure and feels like it was made specifically for the gun. I originally intended to have Tony make one up specifically for the P30sk but never bothered as it works so well.
