I think Ida's Blue is the commoner, it certainly is here in Russia although it's obviously habitat dependent.
One of this hard to separate pair, has a spur on the foreleg I think if I remember correctly, this doesn't seem to have?

From that page,
'Male P. argus have royal blue wings with a black border, white, wispy fringe, and metallic silver spots on the hindwings as well as spurs on their front legs.'
How are you ruling out Ida's?

This is a pretty good shot, surely you'd see the spur?

I'm not, just a suggestion, but those spurs are tiny. Could be either I guess.

I must admit, I hadn't realised it was this tiny and on this basis, I may have to re-evalute my own records.
In that link, her writes
'The upperside male black border is fine and the upperside hindwing space 7 largely blue in P. idas the border often much broader and space 7 lacks blue in P. argus.'
'Upperside'. does he refer to the forewing with this word as the features he mentions are on the underside are they not, mention of the black border being 'fine' and on one shot, of the upperside, it's clearly broad?

This paper by the Spanish entomologist Agenjo (1966) has some very useful info (see Fig. 1): https://archive.org/details/eos-a069p8gf/page/n9
