I am trying to instal an STI extended saftey on my Springer Mil Spec and the sear stop surface interfears with the back of the sear so that it can't be installed with the hammer at full cock. It appears to me that material either has to be removed from either the rear of the sear or the sear stop surface on the saftey. The sear stop surface on the safety appears to be the easier to do. Can you gentlemen give me some guidance here? Thanks in advance

The Thumb Safety has to be fitted. The proper method is to remove material from the stud on the Thumb Safety. Compare the Thumb Safety you removed to the new one to see where material has to be removed. Go slow on this process. A little too much can render the part useless.

I want to say a very big "Thank You" to you gentlemen who responded and also for the PM I recieved in regards to a fitting jig. You all have been very helpful. Nick

Frame safety fitting jig? I'm curious.

Normal fitting is one file stroke at a time. Patience. The sear must not move at all with the safety ON.

Member partsproduction has devised a jig that speeds up the fitting process. Search his messages to find a nice pic of the tool. I for one wish he would make and sell them. Joe

Hmm, it's a possibility, very busy in the shop, just had a guy quit too. Now I've got to train another guy and hope he doesn't get married and have kids and suddenly need health insurance I can't provide.
