| Hi Power hammer problem
I have two Hi Powers both from 1971 era. I bought two spur hammers for them about 10 years ago and back then put one on my Hi Power, the other I bought for my fathers but never put it in. My father passed away and I inherited his pistol and this week installed the spur hammer. My gun works without a hitch and my fathers the same before I put the new hammer in. Since I've installed the hammer in his gun ,it functions normally except, when you pull the slide back for takedown, the safety will not go up into the takedown slot. Without the slide on the frame, safety goes up and down without extra effort , with slide on frame, safety goes on safe and off normal easy movement but retract the slide for takedown and the safety won't move. There is no hang up due to a physical block between the safety and the slide. If I hold back the slide with my hand , the takedown is normal ,reassembly the same. All functions are normal except the safety lever moving up into the takedown slot on the frame. What causes this and how do I fix it?

I 've been testing this pistol this morning and discovered when slide is pulled back to line up takedown slot with safety ,the slide pushes the hammer down more than it is when just cocked , which keeps the safety from moving even under as much pressure as you can put with your thumb. Removing the slide from the frame with hammer cocked safety can be put on but with hammer held back beyond cock position safety will not go on nor with slide on will safety engage if hammer held further back. What must I adjust to sear or hammer to stop this?

Today I decided after a little thought to remove the new hammer after I noticed that with the slide removed pulling the hammer back beyond cocked moved the sear up slightly which at some point before the hammer touched the frame locked the safety and it wouldn't move, if I released the hammer a little and the sear moved down a little, the safety then would move normally so my conclusion was that the slide when retracted to line up the safety with the takedown slot would cause the hammer to be pushed back beyond cocked to the point that the sear then was lifted putting pressure on the safety/hammer pin, not allowing the safety to move because of the sear binding against the safety/hammer pin. I removed the hammer from the Hi Power and placed the factory hammer and the spur hammer both on the hammer pin and the spur hammer was slightly thicker below the hammer notch so I stoned that area to the same contour as the factory hammer and reinstalled the spur hammer. Everything now works correctly with safety function normal and with takedown, the safety moves normally into takedown notch. I also removed the magazine disconnect on both of my Hi Powers and trigger weight of pull on both dropped from around 6 1/2 lb. to 4 1/2 lb. and both are much smoother and with little creep. Sometimes it is better to think about how to solve problem before acting to solve the problem.
