I think the beaver tail would snag first. These Chens are pretty slick.

Chen Full Custom Rear Sight

I was looking at the Heinie because they use a taller front post sight which is similar in height to the Millett dual crimp that im stuck withLots of great suggestions for rear sights. If you are going to something much lower, you're probably going to have to do something with the front sight as well. Given you have a Millett rear, you might have a Millett dual crimp sight in the front. And that will raise its own issues for changing things out.
No sights. Go bald.I have never carried a 1911 and am thinking about adding a Combat Commander to my CCW at my next qualification. I recently picked up a Combat Commander which had a target rear sight on it and I would think that it sits up way too tall. For those of you who carry 1911s, what rear sight do you prefer which still gives a good sight picture but wont catch a shirt or other clothing when pulling? Lets see your carry guns and what your rear sight looks like.
Thats what I use on my carry LW Commander.The Harrison Retro and 10-8 NM are both nice options if you don’t want to get your slide machined.
