Sell off rosters out of state and buy them back in CA?

[Zequa]

The situation is that I am currently stationed in VA (active duty) and I am a CA resident and will be PCSing back to CA shortly. I have off roster handguns legally purchased here in VA that I would like to keep, but would unfortunately have to get rid of unless I find some alternative solution.

A solution if have thought about which is unique but I'm unsure will work is that I also have a friend who is active duty and stationed here in VA and will also be PCSing to CA roughly around the same time (weeks difference). He has had nothing to do with CA in the past and it will be his first time going there.

Would it be possible and legal to sell him the off rosters via PPT while here in VA, and then he would bring them to CA since they would be his, then at some point down the road within window, I could purchase them off of him via PPT in CA? Would this be considered a straw purchase?

This is a particular situation that is confusing and I can't find anything else about this in particular, so any advice or replies is appreciated.
