We currently don't have a CCW provision in Wiskonsin, but that's about to change with our new Conservative Governor, Scott Walker!
While I did learn to use the XSBD sights we had on Judy's G19, I did find it awkward going from the more traditional sight picture(s) to the XSBD sight picture...
This is from my well-received Night Sight Review...
XS Big Dot
sights are high quality combat sights, designed for SHTF situations. Place that big white dot on center mass, and if your trigger control is good, you will hit your target, out to 30-feet or better. The night sight picture is pleasing and easily picked up. These are a specialty sight, and many will find them wanting for range use; conversely, others will master them for target use too. More than any sight I know of, people like them or they don't.
FWIW, Judy's shooting with her G19 improved immediately when we swapped the XSBD sights for Trijicons. My son's shooting with the G19 improved as well. I also noticed that guests to the range also shot better with the Trijicon's more traditional sight picture.
I gave the XSBD sights to an expert-friend (this guy owns 50+ firearms at any given time and has been shooting since he was a kid) and he didn't exactly give them a rave review either...
Conversely, I am well aware that some people master these sights and prefer them over all others!
I'd give the AmeriGlo Operator sights a look-see... The have a similar advantage to the XSBDs (white marker on the front sight only), with a more traditional sight picture... As with the XS's, the lamps are Trijicon.
offers the best selection of night sights available. Quality is first-rate, as the sights combine Trijicon lamps with white PVC O-rings for markers. A combination of sight profiles, blade and notch widths, marker configurations, sizes and lamp colors, offers something for everyone. I really like their Operator sights with a green front and yellow rear lamps!
