Well, I guess it would depend on what you expect for quality. The holster appears to be made for a compact or a sub compact and the gun appears to be even smaller possibly an XDS maybe ?
Remolding a holster for a similar size gun can sometimes be done but remolding a holster for a much smaller gun will look horrible and will not keep it's shape very long without also adding more stitching.
I would rather see you get the right holster and send that one back. If you can't find the right holster, have one made. There are many holster makers right here on this forum that will be happy to accommodate you..
