The centre has been putting in fine displays in international colours but he's struggled to reproduce that form in a Glasgow shirt.
He finally showed that international form last weekend against the Dragons when he scored one try with a classy outside break and created a number of threatening attacks.
In all, he produced eight clean breaks, which would have equalled the Guinness PRO14 record had it not been for Adam Hastings, who set a new top mark of 11 breaks in the same game.
"Getting a good game here has been quite nice for my confidence," Jones admitted in the Evening Times. "I've never really felt that confident in a Glasgow shirt, so it was nice to settle the nerves a bit, especially at home. I'm looking forward to the upcoming games.
"I still get nervous with every game I play. This was my first actual pretty good performance for Glasgow so I have felt that the pressure has been on.
"The fans expect, the coaches expect and, obviously, I expect, a lot from myself. I set myself high standards and if I don't meet those then I get disappointed about it - so I do put a little bit of pressure on myself."
Jones missed the end of last season after getting a bang on the head and then the Scotland summer tour to have surgery on an injured wrist and made his return to action on Glasgow's mixed trip to South Africa, coming off the bench as they trashed the Cheetahs but starting in the defeat to the Kings.
"I'm feeling good - the wrist is fine, so I am feeling fit," Jones said. "I was able to do plenty even when I wasn't allowed to do contact or catch-and-pass during pre-season. I did a lot of cycling, a lot of running so my fitness is fine.
"I've not had many but I'd say that (the Dragons game) was probably my best performance for Glasgow so far. It was good to get out there and secure a nice win."
