Congratulations on your beautiful RBL.
When the RBL-410 was first announced I handed Lou my credit card at the January 2012 Las Vegas Beinfeld Show. I also got double triggers, slim forearm and straight grip stock but they were only offering 28-inch barrels at that time.

Even though it weighs about 3/4 of a pound less than my other .410-bore doubles, because of the tiny frame it has much less weight between the hands and is much easier to shoot. Perhaps the beavertail would have given a bit more weight forward, but I much prefer the slim forearm for looks.
