If I'm not someone who likes to have more than 4-5 mags for each of my guns, is there anything wrong with using US made followers and floorplates for compliance parts out of a desire for simplicity?

I see the point that if I used someone elses mag at the range my gun would technically be out of compliance but considering I wouldn't ever have my gun without my mags that would likely never happen.  

I want to use as many factory parts as I can on my Romy kit (save a g2 trigger group) which would make mags a perfect target for compliance parts.  That would make my 6 parts: G2(3), Reciever(1), follower(1), floorplate(1).  Then again I could get the same out of G2(3), Reciever(1), brake(1), grip(1) and be able to shoot any mag I please....

Help me decide, what do you all think?

the floorplates and followers are what I use

The plates are about $1.80 and the followers are around $3.50.
