you will need a torque spit and a ratchet.
you could probably buy a cheap set from super cheap.
usually cheap enough to buy in a set although i think the one you want is a T35.
a bit tricky to fit if you r fitting one on a semi automatic and if you fit it wrong the cylinder will come apart and piss out fluid from the bell housing.
you can re assemble it but not something i would recommend if your not confident
