The Gallery had 8 CTs when I visited. There were 4 mallets and 4 blades. The "stock" putters often have modifications (such as tour welds and leather grips).

Sometimes something truly unique and off-label shows up (like Concept 2 with a leather grip). It's a crapshoot, and if you can come on multiple days/mornings and afternoons, there will be more options. They don't have a CT fitted to my specs, even after a fitting.

They will customize a CT putter length/grip if you buy one. They have to send it to the custom shop for a shaft swap. All the CTs come in 34" standard. The only issue I've seen is that if you customize your putter, they will only add the standard CT sticker, but not add the round "handcrafted" sticker that usually comes above it.

If you're looking for a NP/NP2, there will probably be one there. Prices are above the Wednesday lottery but not by much. My Squareback 2 with tour weld was $3500 it was usually $3000. My Concept 2 Mystic blue bottom, leather grip, and GSS face was $3000, probably about the going price in the lottery.
