Hi, What could be the cause for a 1911 hi cap 40 s&w pistol to fail to feed with the slide half way with the cartridge rim just right under the extractor but would just not want to go straight in. I have heard many different thoughts but would like to get your opinions what should I be checking? 1. Extractor? The extractor appears to have good tension 2. Overall bullet length? I am using 180 gr. SWC FMJ ammo. What bullet weight has a FMJ Roundnose? Is it the 200 gr.? Im seriously thinking it could be the ammo. 3. Magazine spring? I can feel there is fair tension on the spring when it is fully loaded but how can one know whether there is a need to change mag springs already? 4. Is it likely that the recoil spring is too stiff at 14 lbs? Is this a factor? Ammo has a power factor of 155. Any thoughts greatly appreciated. Sorry but the picture appears to be a bit crappy Wanna kill these ads? We can help!
