Called LOK and told them the second pair fit like the first. They said send them both for a full refund. I told them no, send me a set for a shadow 2 and don't worry about the $10 difference (the Tanfo's were $10 more).
Ordered a set of lava grips and got them in a few days. Very tight fit. Wound up reliving the screw hole and screw head relief slightly on the right panel to not cross thread. Not as thin as the LOK's, but thinner than the wood it came with. They're like skateboard tape in texture and feel great in the hand. They flex a little out of the package, but can't feel any once mounted. Rather happy so far. Was hoping to shoot with them today, but it's the weekend so it's raining...
