Ive probably shot less than 250 rds out of my 1911...I only have two mags, the stock mag, and a cheap "GI" mag i picked up at the gunshop....everyonce in awhile I get a FTF...its been awhile and i didnt really try and diagnose it so I cant say for sure if it happened with only one mag or not....
ALL ammo ive shot has been reloaded ammo from a reputable gunshop/indoor shooting range. What happens is when a particular round tries to chamber, the front of the case/shell gets caught up on the top of my barrel chamber? sorry dont know the correct terminology...and peels the brass back a bit, off the bullet and is unuseable.... anyone ever experienced this before? what could cause it? thanks |

You're short some information for solutions.
Here's what I want to assume. The one stock magazine is a working hybrid. Meaning its made to feed ball and swc. So with assumption in mind. I'm gonna go with an ammunition issue. Just because someone says they know how to reload doesn't mean much. There's press operators and there's handle pullers. What's important to know is two numbers. One is cartridge oal and bullet type. Two is loaded case mouth diameter. Measurement at top of brass, opposite case rim. Should be between .469 to.471. What I think I'm hearing is an occasional out of spec cartridge. Measuring entire box is a good thing or simply take your barrel out and case gage each cartridge using barrel chamber. Should drop in and out. I'm suspect your club is using assorted brass. This presents a problem, different brands have varying case wall thickness. |

when issues occur it is always wise to step back and diagnose by A) using a mgazine of know quality- even if it means borrowing a magazine from a friend -honestly just buy a couple KNOWN good quality mags- like wilson chip mccormick or les baer. you need more than two anyway. one variable eliminated.B) use factory ammo- another variable eliminated
c) make sure pistol is lubricated if you do all the above and have malfunctions then try to diagnose the problem. i'd bet there's a 95% chance after you eliminate questionable ammo and mags that everything will run fine |

For instance Tripp Cobra is timed to release cartridge later than Wilson 47d. Wilson ETM falls between the two. Choice of magazine depends a lot on cartridge oal and bullet shape. Having these 3 magazines covers feed ability much better than just one make. Differences are evident when compared side by side. |
| I know what you mean 1911 smith, realistically most people are not going to go out and buy one of each of three different mags- our points though are the same a good quality mag is needed for a baseline assessment- your idea of one example of several brands is a good idea since there are variable as you point out. gun show parts box bargain mags are not the place to start, and we all know unfortunately magazines that come with factory guns are often lacking in quality as well. |
