The Griffin has a top speed of 86 KPH, with a 275 engine augmented by 5 jump jets. It is considered to have average mobility for a Medium mech.
The standard 1N variant mounts a right arm PPC and a right torso LRM10. The mech is listed with three missile and three energy hardpoints (thanks Bront!). Like the YLW, this would allow the entire left arm (and torso) to act as a shield.
The 1S variant removes the PPC in exchange for a large and two medium lasers and four more heat sinks. The LRM10 is exchanged for an LRM5. This would add two energy hardpoints at a minimum.
The 3M variant uses Star League technology, upgrading the 1N's stock weapons to an ERPPC and LRM20, as well as using an XL engine. This suggests similar hardpoints but considerably more missile tubes.
