Looking to upgrade my factory sights on my G19/4. I have a extremely hard time getting the front sight focused crisp and clear. I shot a Springfield XD the other day that had factory sights (red front with all black rear) and I didn't even have to try to focus the front sight it was freakin awesome; it allowed me to acquire my target so fast and I shot much better than I do with my Glock. Anyways my question is, I'm looking at the TruGlo TFO's but I'm worried that perhaps the two rear dots will slow down my focusing of the front sight? Should I get all black rear with a front night sight? Or will I be fine with the front and rear TFO's? My main goals of upgrading are acquiring my target and getting my front sight crisp and clear as fast as possible while shooting accurately. Thanks Wanna kill these ads? We can help!
