I just picked up a Colt XSE Lightweight Commander (100 years of service model) my plan is to have some modifications and upgrades done.
I plan to make it a Bobtail and I'm going to do that myself, I already purchased the Ed Brown Bobtail mainspring housing and I borrowed the Ed Brown jig for doing the mainspring housing retainer pin.
I'll post more pics and updates as I have them.
Here are the before pictures.
