Which laser/light combos for an handgun picatinny rail do I want?

[Pond, James Pond]

Gun: SP-01, so regular accessory rail.

Dad is in Texas and so may ask to have a look around if he sees any gun stores.

However, he is neither expert nor going there to shop for my toys so can you recommend a decent laser/torch combo that would fit my SP-01 which is likely to on the shelf in any relatively decent gun-store?

Also, what budget should I expect?

Finally, can anyone confirm for certain if someone can buy them and then pack them away in a suitcase? Is it one of these controlled items?
I know optics are out, but surely a torch is OK.

I can buy a meeting room laser pointer and a hand-torch anywhere, but put the two together with a rail attachment and suddenly it can get weird. You just never know and I don't want one of my dad's holiday memories being arrested at the airport!!

Sure-fire makes an INCREDIBLE product, but its expensive.

You might want to check with some companies to see if exporting laser sights is prohibited

I'd also be surprised if a "gun store" had them on hand

A place like Gander Mountain would be more likely to have that sort of thing in stock
