Yes, you are supposed to curl your pinky under. It provides quite a bit better recoil control and prevents the need to reposition your hand between shots when the gun slips. But...lots of guys never tried it, or never tried it long enough to come to understand the benefits of it, or they have and they just don’t like it. I grew up with a Blackhawk and shot pinky under from the beginning, so it feels natural to me. I believe most who give pinky under enough of a fair trial will come to like it and see the benefit of it.
When I started shooting 1911’s riding the thumb safety felt so wrong I swore I wouldn’t be able to get used to it. But, all the top shooters all shot that way so I swore I’d give it a fair and proper trial. Now my old grip with thumbs down feels just plain wrong. Point is, if you made it this far without trying pinky under, you are unlikely to ‘get it’ by firing a cylinder or two through the gun.
