Che Adams now has in his sights Trevor Francis' scoring streak of seven league games in a row
His terrific record so far and his performance at Loftus Road - his treble came in 21 devastating minutes - has seen him pass some significant milestones.
Adams opening goal took him to 17; the last Blues player to score that many in the league was Mikael Forssell in 2003/04.
Forssell, in his first campaign for Blues in the Premier League (on loan from Chelsea), added two more to his tally in the FA Cup.
Paul Devlin bagged 16 league goals in 1996/97 (19 in all competitions).
And when opening the scoring, Adams matched Devlin's feat of scoring in six successive league games (completed in August 1997, straddling over two seasons).
Now Adams has in his sights matching Trevor Francis' scoring streak of seven league games in a row in 1977/78.
And, of course, one more goal will take Adams to 20 - a feat last achieved at Blues by Steve Claridge in 1994/95.
Claridge scored 20 in the Second Division (old third tier), one in the League Cup and four in the Auto Windscreens Shield.
Blues other notable goalscorers in modern times were Nigel Gleghorn (17 league goals in 1991/92) and Dennis Bailey (18 league goals in 1989/90) - both marks passed by Adams at QPR.
Paul Furlong scored 19 times in all competitions in 1997/98, with 15 of those coming in the league.
Adams triple salvo on Saturday was his second league hat-trick.
He scored three for Blues in the 5-1 League Cup defeat of Crawley Town in August, 2017.
His maiden Championship treble was against Hull City in November last year.
