The slide comes with some ports in it but no popple holes as 9 major doesn't benefit enough from it it. I have an Infinity steel grip on it. It is also a short dust cover.
I also have a BUL armory Bullesteros full dust cover that I rebuilt with the an Atlas open style slide. No cuts, all the metal along with the grip and it shoots balanced too.
7lb ISMI recoil springs in both.
