** I understand anyone who replys to this post assumes no legal responsibilities written or implied. so just share your experiences ** I am a happy owner of secondhand XD9 4" Just one concern, my box says "Not legal in California" hm... so my search results came out to "10+ rd mag is a high capacity magazine therefore assault weapon" well, then there was another result said, 3 ways to have XD in CA. 1. Have your direct family sent it to you as gift (not sure how this works, but doesn't matter because i'm not doing this) 2. get a 10rd mag and get approved - afaik, springfield doesn't make 10rd, so a big no no. 3. "if you buy it out of state, and move into Cali, then it's ok" (plus some registration and stuff) SO it seems I should go for option 3. now..... I'm starting to gain interest in big caliber rifles for long range. (I mean, I moved up from 10yd to 20yd, then went out to outdoor, did 25yd, and a 30'x30' cardboard @ 100yd yes with a 4" barrel 9mm,, and now i'm bored) I was just wondering, if I can buy a 50cal here, and then bring it into california as I move to CA. so,,, two things 1. Can I keep my Springfield XD9 with 16rd mag?? 2. Can I keep my .50 Cal whatever rifle?? and one more +. Should I go through 308 Win. and other stuff before 50cal? I do understand I can't jump up the stairs... so RECOMMENDATIONS PLEASE~~~ but i love that near-kaboom of 50cal. don't you?? ** I understand anyone who replys to this post assumes no legal responsibilities written or implied. so just share your experiences ** I will only use them as ballpark guidelines, not legal advices.
