I am not god of 1911s. I had not owned one for 8-10 years when I got my Colt Gvt 70 series last week.
I shot it yesterday for the first time using some new American Eagle 230 gr ball although I generally reload. Got some weird(to me) ejection pattern and flat spots on some rims. I shot mostly with a two handed grip. The brass ejected in three little piles. Right at my feet, just behind me, and then one piece would go way behind me. I even got several pieces right back in my face. On about half the brass, I got a nice flat spot on the rim. Could this be due to too light of a factory recoil spring to handle the rounds I was shooting? I shot 50 rounds and they seemed rather peppy. My reloads generally exhibit much less recoil. Other than that, the gun ran and shot very well. There were no stoppages and accuracy was pretty good. |

No stoppages means soldier on do not mess with anything, with 1911's trying to tweak things just to change ejection pattern is an easy way to create a non Functioning paperweight. If you want to try a heavier recoil spring ( easily reversible
If it causes problems ) that is ok but don't go looking for trouble And yes while you might get lucky expect any part replacement in a 1911 to require fitting |
|
Maybe the biggest thing I wanted to check was if the case dents were common.
I just don't remember if my 1911 I had years ago did that. My current gun is brand new and I don't want to make any "changes". If the recoil is too weak to shoot that particular ammo, I will just try my weaker reloads to see if that helps that issue. Of course, both the ejection and dents may be related. I don't care about a little brass hitting me in the head. I wear glasses anyway and I only intend on this gun being a range toy. |

Quoted:
has the ejection port been modernized? ie lowered and flared Is the extractor clocking (it should not) and of correct tension? 16lb recoil spring is standard for 230 FMJ @ 830 fps (ish). I believe that America Eagle 230 grain FMJ is loaded to a muzzle velocity of 890 fps making it the hottest of the widely available 230 grain FMJ loadings. It's loaded closest to the original specification of 230 grain .45 ACP ball of any other 230 grain over the counter stuff. I'd try some other ammo before making adjustments to the pistol, or up the recoil spring to 18.5 lbs. When shooting 230 gr AE I use an 18.5 pound recoil spring which I find works well for all other factory loaded 230 grain FMJ. |

Here is something for you to try. On your next trip to the range, do this test.
1. Chamber one round from a magazine. 2. Drop the magazine. 3. Fire the round. 4. Repeat until all rounds in the magazine have been expended. If you get any kind of erratic ejection or if an empty case falls down the magazine well, your extractor needs work. |
