Just looking for anyones thoughts on this: While firing my 1911, the slide was not moving completely back to the forward position. I could barely touch it with my thumb, and it would go the extra couple millimeters and the fire. Put just a small little touch of CLP to help it out but there was no sign off a resistance issue. Possibly the magazines I was using. The rounds were feeding fine, but just the slide was rocking forward completely. Thanks in advance! |

Factory ammo or reloads?
If reloads try removeing the barrel from the gun and dropping the rounds into the chamber (useing it as a gauge). I use oil on most of my guns but have always used grease on my 1911 rails. Brand new build might be a bit tight don't get too excited untill you get a couple hundred rounds through it |

A few things come to mind.
1 - excessive extractor tension or improper beveling. Cartridge rims are not fully camming under the extractor hook due to sharp edges or excessive tension. Sometimes the rounds will even get ahead of the extractor, which means the extractor will then snap over the rim as the slide goes into battery. 2 - barrel bump. Occurs when lower barrel lugs are not properly relieved for clearance, and the high spots can hang on the barrel lugs. This will manifest as a hesitation or "ka-chunk" as the slide returns to battery, and will show up as peening on the convex curve below the lug flats. 3- rounds fighting past the slide stop. Energy of slide return is wasted as the nose of the cartridge has to squeeze up past the slide stop lug. This shows up as a brass smear on the inside of the slide stop lug. |
