New firing pin and springs

[venison]

Where would you guys get a new firing pin and a complete set of springs? Drop-in parts within USGI specs--not too tight for reliability.

I'm asking this because many brands seem to sell "improved parts" at "improved prices" for which I do not know how good they are.

There's Les Baer which has a nice set of springs and pins but I guess (as in I'm not sure) I have to buy some extra springs apart.

There's EGW as well but I'm not sure whether their parts are standard or "tight fit" [for match guns].

Eventually, I may consider a drop-in trigger kit someday. "Carry pull" --nor match neither a lawyer one--, blued, hammer shapped as in a 1911A1. Which kit would you choose?

Hi

Wolff is pretty much the default place to get spring sets. A standard set is what you are after. Ed Brown parts are pretty easy to find, his firing pins are as good as any for the price.

The rest of the stuff I'd rework in place rather than mess with one of the kits. If you are concerned with reliability, rework is the *only* way to go.

Wolff or ISMI for springs. Cylinder & Slide for trigger kits. Which EGW parts are you talking about? Their bushings are second to none.

Where to get all these? Where else? Brownells.

First, I'll buy a firing pin because mine it's bended [what may have happened?]. As I have to buy that firing pin I may add a firing pin stop. I've seen many firing pin radiuses advertised. I understand I must go for a .090" one.

As for the spring kit I've seen them advertised [Wolf] with a heavy duty firing pin spring and a heavy duty mag. spring. Do I really need that heavy duty [+40%] firing pin spring on a Series 70 carry gun? Won't that pose any sort of problem? As for that mag. spring do I need it "heavy duty" for ball spec loads?

I've seen Ed Brown sell a rebuild kit for the trigger springs and plunger tube that includes some pins. Sear spring, recoil spring apart.

Those are the things I need now. Trigger kit, etc may come afterwards.

In general:

- firing pin spring (heavier than normal) it won't hurt.
- Magazine spring, you do need a good spring in your mag, but I am not sure which one is the proper one from Wolff, I think it is the +11% one but you'd better wait 'til Tuner drops in.

A rebuild kit is used if your pins are bent or damaged. I have no idea what the springs in them are. There is no trigger spring in the 1911, the trigger rebounds due to the sear spring.

Where else? Brownells.
Especially when you can get to the website, right Boss? ;)

I'm afraid I should have added that this specific gun has discharged no more than 10 rounds since NIB yet that firing pin is bent [arched]. That makes me "distrust" the other springs, pins, etc. I figure it's better to err on the side of caution.

For what you said I'm going to get a Wolf spring kit and as for the firing pin it'll most probably come from Ed Brown--for no specific reason.

The most popular way to bend a firing pin, assuming it *got* bent and didn't somehow make past QA that way, is for it to stick in the breech mortise and be struck from underneath by a subsequent round. If this has happened, and you have that few rounds through it, I'd check the firing pin hole very carefully. It will likely be burred and thereby catches the firing pin. A new pin wont cure this; only redressing the hole. To check, use either a dental probe, or the dummy end of a drill bit.

Hi

Is this a Series 70 from back in the 70's or a Series 70 reproduction? If it's a reproduction, it's still under warranty. If you are swapping around parts, save the originals.

The spring kit will be:

Gunsprings.com
Pistol Service Packs
Colt 1911 Series, .45ACP
Stock No. 69142 - Type II

As for the Firing pin:

Ed Brown
Ed Brown Hardcore
EGW .093"
Briley

I do not know much about MIM, investment casting, ... which one should I choose? Would .093" be too tight?

Hi

From what you've said already, either of the Ed Brown's will do.
