Can someone tell me how long the recoil spring is for the commander size .45 recoil spring.
Oh, and for the officer size 45 too please. All I can find for measurement is weight. Thanks Doc |

Similar pistols but with shorter slides, such as Commander or Officer’s ACP-length models, require springs that are not only shorter, but have different compression weights. A standard Commander spring is 18 pounds when compressed to 1.125", while the Officers ACP spring system must store 22 pounds of energy when compressed to .700". The free length prior to compression is not all that important, as long as it fits within the available space.
These figures should explain why the shooter cannot take an 18 pound full-size Government model recoil spring and shorten it and expect it to function the same as a standard 18 pound spring in his Commander-length pistol. from: http://www.brownells.com/GunTech/1911-Auto-Recoil-Spring-Compression-Weights/detail.htm?lid=10262 |

A (very) quick google search reveals that nearly everyone selling springs describes them soley by rate, as previously posted in this thread. The only discussion about length I could find quickly is here:
http://www.thehighroad.org/archive/index.php/t-615164.html Various spring rates are listed on Midway: http://www.midwayusa.com/product/3415160533/wolff-recoil-spring-1911-commander In other words...it doesn't really matter how long they are, but more what the spring rate is. |
