My Sistema's hammer bites like crazy.
From what I can tell the hammer is the the long spur type. I am told it is the original 1911 type. The grip safety also is also contoured differently than the "GI" models I have seen. I am also told that I can use the shorter spur "1911A1" hammer in this gun. What else will I need to change, grip safety?
I don't want to make any permanent changes, just make it more shooter freindly.

I would appreciate it if somebody could shed some light on this for more. I don't remember any significant hammer bite from my old issued 1911A1.

1911A1s had a reputation for biting until Colt finally shortened the hammer somewhat in 1939. Any narrow spur-type 1911A1 hammer will do, or if you want to keep the original look you can do what I did. I bought a King's Gun Works wide-spur hammer, then shortened it to the post-1939 profile.

Your grip safety should be the standard 1911A1 profile. If not then somebody's replaced it.

It often ain't quite that easy. Under recoil the flesh of the hand rides up over the grip safety, and it gets pinched by a too-long hammer regardless of whether it has a sharp edge or not. It's too subjective however. For me, any long wide-spur will bite me. The short wide-spur doesn't. But the narrow spur of a Remington Rand or new Colt Government will. And yet the spur hammer on my Ithaca doesn't.

Go figure!

There is a gun show coming up in about a month. I will look for a short wide spur hammer there. There is normally a guy with lots of parts. He is also pretty steep on his prices. Until then I think I will install a spare McCormick hammer and sear along with an old Officers acp grip safety and thumb safety. I want to avoid modifying any original parts until I can get what I want.
I like the original equipment look and feel. But, not the bite. Youch!!

Personally, I'd just order one from Brownells and shorted it if necessary. They also carry a cast hammer from Masen that replicates the short/wide Colt hammer.
