I have an S&W 6946 9MM. It was my grandfathers First semi automatic duty pistol. I replaced the recoil spring and cleaned the weapon. I also replaced the stock grips with new stock grips. Originally I thought it was a specific problem with the 15 round S&W 5906 with spacer magazine jamming. I ran the original 12 rd mag with No jamming issues the first 12 rounds.. Switched to the 2nd original mag jammed on the 3rd round.. Switched back to the 1st magazine and started jamming on the third round also. I tried multiple types of ammunition including Winchester White Box still jammed... the jamming became progressively worse as I shot more rounds..
I am well aware of the DAO trigger system..
I checked the extractor with a dummy round the extractor holds the dummy round without issues.
Could it be the 30 year old magazine springs?
