There's clearly a tendency to put more pressure on the lug when you're shooting a gun with a beavertail than with a splinter--where you're scarcely gripping the forend.
Well Stan, you followed that with a discussion about the purpose NOT being attenuating recoil . . . which I never said it was. The reason more people are likely to apply more pressure to a BT vs a splinter seems pretty simple to me: because there's more to grab. Whether they SHOULD grab on hard is another issue. But it's quite clear that they can, and that some will.
You're ONE gun buyer and I'm ONE gun buyer. So we're clearly both entitled to opinions about the advantages we might see in a BT. But while a BT will protect your hand from hot barrels, how big of an issue is that for the majority of American sxs shooters? The sxs isn't a terribly popular target gun, other than at sxs shoots. For most owners, it's a hunting gun. And there simply aren't too many situations in which you're going to get your barrels hot enough to burn your fingers while hunting. IMO, of course.
