Yes it is vindi...
I am thinking it is also the 9mm spring guide.. So the stock spring probably wont work. But I do have my eye on a PDI 130 spring. With just the spring should get around 380 fps from what I have read. So should be right around the 400 fps I am looking for with a really good seal and what not.
