I just got a CCW and been carrying my Kimber Classic 1911. I carry it cocked and locked. My questions is since the mainspring is under stress all the time during the cocked and locked, how often do you changed this spring on your carry weapon to ensure reliability? Do you do the same on the sear spring and mag spring? Thanks for your advice in advance. 556man |
Good recomendations. I'm not disagreeing, but I've never seen/heard of a mainspring failure. I change mine too, but I've seen plenty of WWI and WWII pistols that have some OLD mainsprings, and they work fine. When the other springs get weak, bad things start to happen. The mainspring is one of those things that is over engineered. It could be as low as 18 lbs. and still function well. |

I would say change it every 100years or so. I have at least 20,000 rnds through my Colt Gold Cup over 15yrs , and the main recoil spring is the only one ever replaced. If you cock the hammer and it has tension, yep you guessed it it's still a spring. Magazine springs also get changed every couple years. |
You wont go wrong with either Wolff or ISMI. If you have really picky needs for certain loads or are trying to get a certain feel out the gun, those two companies have products to fit your needs. On a defensive gun, I'd just go with the recomended weight. As far as not replacing the mainspring, you're probably right, but at a few bucks a spring it is VERY cheap insurance that will ensure a reliable pistol. |
| Even if you have it cocked and locked for carry, you may want to let the hammer down overnight, unless this is your home security weapon. Kimber suggests that you let the hammer down when not in use. But there is no real time to know when a spring will malfunction. Keep parts new and up to date. Your life is worth more than the $10 spring isn't it? |
