I purchased this 1911 Springfield Lightweight Champion off another forum.

 I have never owned a Champion or Bobtail , I can tell you they are a pain to take apart and even harder when you don't have the factory take down tool.

 The dual spring is something different I have never had before. Is there a way to have a single spring or the factory dual spring is the way to go?

 How often do you replace the recoil spring setup?

 Not sure I like the straight trigger, another first for me and some serious range time I will know more.

 Listed is work the previous had done by Drake's Gun Works. Not a gunsmith I know but after taking the pistol apart and doing a detail cleaning looks like quality work.

-Frame anodized-Slide treated with melonite (they are an exact match)-Carry bevel the pistol for smooth surfaces-Install Dave Berryhill ignition set (Hammer, sear, disconnector)-Install 10-8 flat serrated trigger and tune-Cut and install Ed Brown checkered bobtail MSH-Fit Caspian ejector/extractor-Fit Wilson Combat single side tactical thumb safety-Fit Wilson Combat slide stop and flush cut pin-Replace all pins with Wilson Combat pin set-Custom DGW sights with a tritium front sight-Wolff recoil spring cut for this gun (includes extra)-Fit Wilson Combat plunger tube-Properly fit existing grip safety-VZ thin G-10 grips with hex screws/bushings

And no the idot mark is not from me, lol. Had 1911s for years.

Looks good to me. Enjoy it.
