Just received new info from LWD. They advised that within the next 3 weeks or so, G37 and G38 barrels will be available (G39 currently available on-site). Great for keeping reloading costs down with lead bullets.
I had thought about getting a GAP, but was turned away by a rude comment by a moderator on this forum, and the fact that I couldn't find an aftermarket barrel for shooting lead.
