9mm 1911 slide locking back, under recoil, with rounds still in mag...
Finally got my "Beater Pistol Project" 1911 fitted with sights. Excited, I went to shot it and... about every 3 or 4 rounds, the slide is locking back under recoil. At first I thought I might be having feeding issues, but, it is definitely slide lock engaging.
With Glock and Beretta I would just install an new spring in the slide catch. With a 1911... not as sure what to do.
My first thought is to replace the spring in the plunger tube. My other concern is, this pistol has been ceracoated. So I am wondering if the coating on the slide catch is somehow allowing the part to move more freely under recoil?
