Sorry guys, I took a photo of the holster sans the pistol and then put in the revolver and didn't realize it wasn't all the way in.
This is how is should have looked:
If you look at the holster Stobie has and you look at the top of his belt, you'll notice the top of the belt crosses the gun at about the trigger level. If you look at the loop on the back of the holster shown, you'll see the top of the loop is at the trigger level. If you still don't like it, don't blame me, blame Hickok, it's a copy of his fish scale holster, including the nearly square loop. I'll try to find the original and post.
With the proper belt- no problem. In fact if I balance the holster on my finger at the top of the loop the balance is strongly towards the muzzle.
That said, I'll also try to find some period pictures of guys from the 1850's and 1860's with slim Jim type holsters, a lot of times they are flopping around or angled on the belt. When I said the Slim Jim type tended to be top heavy what I meant was compared to the Mexican double loop style. On my great grandfather's Mexican double loop (circa 1880) the belt crosses the holster at about the top of the hammer rather than the trigger, way higher. I've never heard of anyone having a problem with the double loop style.
And.. the Hickok holster was rounded, I think the Stobie is that way although hard to tell from the photo, in any event it didn't have a bottom plug.
