Sometimes 2nd best isn't so bad. Look at the German G36s they can't even shoot straight.
Italian would be the better option considering Pakistan wants to equip it's Army branch, the ARX will be the final "trojan" into the Italian Defense industry. Falco, Westland, potential Salex.
$10 Billion LOC for Italian investment into Pakistan, support for a EU-PAK FTA, 100,000 + Pakistanis already living there, not to mention a great share of raw Pakistan exports end up in Italy for manufacture.
The hands from which Pakistan can buy from without Indian interference is/will continue to dwindle. Start a relationship early and the other person will remember it later on.
