For the tactical gear, you may want to take a look here :
www.taiwangun.com
It's based in Poland, cheapest airsoft gun shop in europe and recommended by a lot of well known airsoft forums. For the guns, a pair of glock 26, I recommend airsoft guns too, you'll find several version of it here :
Search results for: 'G26'. It's also a trustworthy well known airsoft shop, I've personally used multiple times.
Depending on your budget, I'll go either with two KSC metal slide gas blowback (
KSC G26 Gas Blow Back Pistol (Metal Slide Version)) if your budget is large enough, you'll have something really realistic, that looks and feels just like a real pistol, nice metallic sound when you release the slide etc... You can even push it further by filling them with airsoft gas like this one :
Green gas 1000ml / Gazy i Smary - TaiwanGun - Militaria, sklepy z broni and by blocking the slide catch, so when your girlfriend will squeeze the trigger, the gun will cycle like a real gun except the flare of course, and it's totally safe (as long as you don't put bb pellets in the magazine).
But if your budget is tight, I'd go with these Marui G26 spring pistols :
Tokyo Marui Gindan Glock 26 RF Spring Pistol (Black) They look the part, but they're plastic and unlike the KSC, they won't cycle like real guns.
Regarding the thigh holsters, they are Blackhawk CQC Serpa left and right handed :

You can find a cheap airsoft copy with leg straps on taiwangun (
Kabura na platformie udowej z mo) but it's not made for the G26 model, it should still fit but it will be longer than necessary and it only exists in right handed. The leg platform on the cheap copy should however be able to receive a real blackhawk holster and is ambidextrous, so you could buy two of them from taiwangun for the leg platform, and a left handed + a right handed real CQC for Glock 26 from ebay, then assemble them for example. Or you can keep the right copy holster, even if it's a bit bigger, and buy a left handed blackhawk cqc for standard sized glock (17, 19...) like one of these :

I also saw a thread somewhere here with urethane shield logo patch, you'll need two of those for each shoulder, but one has to have the eagle looking at the left, and the other with the eagle looking at the right, so both eagles will point towards the front when fixed on the shoulder.
Good luck !
