Interesting Call to Colt

The mainspring forces the hammer down on the firing pin; we all know that. But another thing that it does is maintain pressure on the hammer as it bears against the recoiling slide, giving some resistence to the slide during the firing cycle. This gives some support to the lockup of the gun when the hammer isdown, and later affects the velocity of the slide in its rearward AND forward cycle. You can lighten the mainspring and still have the firing pin strike hard enough, but you may be adversely affecting the velocity of the slide, and thus wear and tear may be higher. All things to think about.

I've had good customer service from Colt. My first Series 70 Repro had the trigger pad brazed on crooked. I called them up and explained the situation and emailed them a picture of it. They sent me a new trigger in the mail. This was about ten years ago though.

Besides Hammerdown, Wolff Springs' site lists the standard as 23 pounds, among other people & places that agree.

Re S&W, Colt isn't entirely alone in CS info (or lack of it).
I've gotten bad info, incomplete info, and no info at all from S&W on phonecalls, including one part order they put through complete with credit card info that never showed up. The part was apparently out of production when they let me order it.

Ruger will be vague at times, too.

It's an unfortunate situation that seems to be spreading through the industry, and it's sad that you can no longer call a maker up and get help over the phone on simple questions about their own products.
But, it's not just Colt, and I no longer expect any real knowledge from anybody who answers a CS number for a gunmaker.
Many times they don't have a clue, other times the legal department won't let them go any farther than "Send it in".
I'm pleasantly surprised when a call-taker actually does know the answer to my questions.

I expect hammer spring is not on the parts list, but mainspring is and rather common knowledge, especially with a few keystrokes.

The Colt customer service rep could have just googled the answer.

Now I see why gun companies aren't building more guns. It's because they're spending half the day answering questions.

Why do you feel it necessary to fix what ain't broke ? Colt makes the finest production 1911's on the market hands down .Been doing it for a hundred years . How many phone calls do you think they get from folks that don't have problems just questions they offer to take a look at your pistol if you thought you had a real problem what else should they do. That little girl answering the phone does'nt know anything except how to answer the phone you could have really got Lucky and talked to a machine.

The Colt customer could have just googled the answer.

This would work as well. Many companies restrict who has access to the Internet due to security and productivity issues, among others.

Just follow what was recommended in post #11. I view his advice as consistently right. One of the experts on this forum.

The problem is having a polymer MSH that won't sand like a metal one. If you want something similar to the others buy a Wolff 20 lb. replacement spring and see how it goes. If, after changing springs you're not satisfied, consider a replacement housing and polish work.

Yeah, I don't really see your spring binding up in that nylon MSH unless there's some serious mold flashing in there or something. You should be able to feel it bind just by pushing down the spring in the housing with a punch on the mainspring cap.

My stock Colts have hammers that are harder to cock than some of my others that have been worked on. One of these guns has a 19 lb. mainspring in it, and it's noticeably lighter than on the stock Colts. I'd say you should just order a 19 lb. mainspring from Midway or Brownells or directly from Wolff and that will give you the feel you are looking for. They are cheap.
