I have been looking online and I can't seem to find anywhere that gives a side-by-side comparison of available sights for a 1911. I'm about to buy my first 1911 and I've heard some sights are attached in a permanent manner, which doesn't sound very upgrade or option friendly. There's Novak, Heinie, Low Pro, night sights (tru-glo, etc)... I wish I could see these compared online somewhere. I'm an OTR truck driver and I plan on purchasing my 1911 and having it waiting for me at home... I don't really have much of a chance to go somewhere to see them first hand. I'm debating between a few Taurus and RIA 1911s and one of them even says it comes with Heinie sights on the main description but says it has Novaks in the "Features" tab Need help on this please. Thanks!
