Unsurprisingly, Pete was happy to recount his score after the match.
"Alex Dunbar gave me a great offload and I managed to get on a support line and pick up the ball," he said.
"I tripped myself up a couple of times but I got myself over the try-line. After the first dummy I thought I'll just see what happens but then I got to the 22 I started to realise I might actually makes this.
"I was just delighted to get the try."
Peter admitted Glasgow's European performances had not been good enough this season, but was glad to finish with a win.
"It was great to get the win and finish on a high," he said.
"It by my no means makes up for all of the losses, but it does gives us a few positives to take in for our form in the league season."
Glasgow head coach Gregor Townsend said: "We've shown what we can do at times in every game. We went down to Northampton - who were Premiership leaders at the time - and we were 15-0 up. We were leading for 75 minutes over at Castres, so we've shown it, we just haven't had the 80 minutes and the winning performance until now."
As for the match itself, Gregor was upbeat, saying: "For the second half we had a lot of the ball, which was good, and we were moving the ball around well.
"I thought at times we could've had a few more penalties when we were attacking and trying to play quick ball, but it was great to see that passion and to get the win."
