Just got these the other day and both the 43 and 19 conceal very well...and comfortable. As a lefty, I like to carry @ 9 o'clock and appendix on occasion. Both positions work with these holsters and the comfort level is very surprising. The echo pro carriers are simply awesome. I wear them outside although they're ambi inside or out...great little item. Spend a buck fidy and they give you a free Delta tray you can show off to your friends :highfive:
