I corresponded with Bruce about the .330 Metplat bullet, his website plainly alludes to having to experiment with different seating depth's to get them to feed in a glock. I bought 100 of the coated .300 metplat bullets to see how they fly before I buy 500. It might be wise to email Bruce and ask him about the RIA pistol regards the .330 Metplat bullet feeding in that pistol.
