The Custom Sistema
After shooting a 1911 fitted with an Ed Brown grip safety, I decided that any 1911 I fitted a beavertail to would have one of his grip safeties on it. The Ed Brown grip safety requires the gunsmith to remove a significant amount of metal underneath the grip tangs. As a result, the web of the hand seats underneath the beavertail almost a quarter of an inch higher, placing the shooter's forearm closer to the bore axis for faster follow up shots and reduced perceived recoil. A couple of years back Ed Brown quit producing his grip safety without the "speed bump." That was a regrettable decision from my point of view. I prefer his grip safety, but I don't really care for the lump in my palm while shooting.
In a lot of ways, my modified Sistema is nothing fancy. It still has it's original military sights. The ejection port is GI. The grips are used rubber off a Kimber. The front strap has no checkering and there are no 1* inscriptions on the slide. What it is though, is a consistently reliable and accurate gun. You can read more about my modified Colt Sistema here.
