I found out that Tokyo Marui makes a replica H&K MK23 SOCOM airsoft gun which I can't import since I live in Canada and the laws are silly here. I want to keep my .177 cal H&K USP anyway and just add on the R.I.S. mounted light from the airsoft version since it'll most likely fit. but I can't find it sold separately without having to buy the gun! Woe as me. Any ideas? This would be what I'm talking about.
