I've been thinking about another Glock, and while I am a fan of 9mm for a lot of practical reasons, sometimes you want more bang. My first thought was 10mm, but doing ssome research it seems the 460 might be the ticket. So I started thinking about a G30 to slap the conversion onto. That way I could play around with 45acp, or get a10mm barrel and have that option. But then I saw someone talking about Glock lowers somewhere in another forum. I believe the 460 upper will chamber and fire 45ACP with no problem. Since I have to buy a new upper to get 460, would buying a G30 lower rather than a complete pistol work? It would save about $300.
