Hi, I'm building a 1911. It's a Springfield military model I've owned for 25 years. I bought it new and decided to work it over a few years back. I'm almost done and here's my question. Should I replace the stock springs ? All or just some ? Why and who's should I consider purchasing ? Thanks in advance !

I'd just replace them because they are cheap. I'd use Wolff springs except the sear, for that I'd go with Colt. This. 16lb recoil, 23lb main, use the firing pin spring that comes with the recoil spring but make sure you use a steel firing pin. Also, Colt or Cylinder and Slide plunger springs that come with the plungers are good. I don't reuse plungers. |

5 inch 45, 16# is std.
23# for the main spring. Sear spring I would not replace as your going to have to tune the spring. Hell I would not replace the mainspring if the gun fires. Wolff gunsprings will give you a new firing pin spring to use, ISMI does not. Either will work just fine. Rest of the spring I would only replace if they are a problem. Colt sear springs are the best. So most would recommend them. |

Thanks Number One ! I did a little digging and will definately go this route. EGW is out of stock at present. 
Surprised I had never heard about this before. Now I need to figure out how to tension the sear spring. Any tips ? http://www.brownells.com/GunTech/2-lb-Trigger-Pull/detail.htm?lid=10297 |

Usually guys who use the flat bottom firing pin spring usually use a 23# mainspring. I use a 25# which is what a lot of guys use in the Delta Elite guns (which are 10mm), I've found that this actually dampens/retards recoil even more. There's an alternate source: Wilson Combat Harrison Design Both are in stock. Both are for Series 70 guns. (Mine is a Series 80, so I use the S80 equivalents.) |

I never liked the flat bottom fps. Made the gun feel jumpy or flippy under recoil. I do believe it helps with reliability though. The 25lb main is over/kill.
I like to flat grind the ends on Wolff mainsprings like the original Colt springs. I have seen mainspring stack and it will ruin a hammer/sear in short order. |

As long as the hammer strut is proper length it should be fine. Colt or Springfield specifically, as far as I know. I've had very good luck with this setup so far. I know two people both using Colt Delta Elites with the same setup, and it's good for them. As for jumpy or flippy recoil, for me it seems to make the gun track slower, but flatter. |

If the mainspring is too long/heavy, or the hammer strut is too long, you will put too much pressure on the sear nose. You can chip it over time. 23# is fine. I like 25#. Just curious, has anybody used the Sprinco dual recoil guide system? I was thinking of trying one out. |
