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.
