So what options, modifications, custom work, et cetera would you put on/have done to a 1911? I am thinking about buying my first 1911 but after the basic upgrades I don't even know what the upgrades do anymore. I'm a lefty and I have some understanding of the options available for 1911s so I know that I want: Ambidextrous safety Ambidextrous magazine release Adjustable and/or night sights Lowered and flared ejection port Beveled magazine well Probably a trigger job. Maybe checkering on the mainspring and front strap as well. After that I don't know how effective/useful/necessary these things are: Fit slide to frame Fully ramped and supported chamber barrel and bushing vs bull barrel bobtail mainspring vs normal mainspring (I guess I will have to shoot these to find out) Full length guide rod vs regular guide rod So, in summation, I would like to know what you would put on a 1911 to increase performance, reliability, etc... so I don't blow money on things that don't matter.
