First off, not to put off your question, I'd like to extend a welcome to the forum from the SE coastal plains of Texas and thank you for your service. To be honest, I don't have the 45 version but, I don't remember ever noticing the round indicator while using either of my 9UCs. Since I'm doing a reaclaimination to the BT380 I had to drag one of them out to see what your are seeing. Even being conscious of your question, with primary focus on the front site, I had trouble seeing the round indicator and had to take my eye off the front sight to see it.
