Main spring (Recoil Spring) for the 1911 Government (.45 ACP) *

The standard weight of the main spring for the Government is 16 lbs .. It was designed for a general and reliable operation of the weapon.

The weapon had to work under all conditions and also with the ammunition of different manufacturers. Here also a weak holding the gun (the one-handed shooting), temperature and climate variability was taken into account.

16 lbs. is for shooters often too weak and the frame of the gun loaded pretty strong! Therefore, it is like looking for a adjusted to the ammunition spring.

What nib should you use?

The most asked and perhaps the hardest question to answer!

There are many factors that affect this question: the ammunition used (bullet weight, bullet shape), the gun used, the shot discipline and of course our own feeling.


    Basically, the hardest springs with the weapon under
    the conditions necessary to function properly,
    is the best!


A good indicator for determining the correct spring: it determines the distance from the gun to the area where the sleeve first hits the ground (will not be)! Here, an observer should determine the impact of more than one series. Important is a uniform attack, as the discipline is shot.


    The ideal distance should be between one
    and two meters (3 ft between 6.5 ft)!
 

If the distance is greater than 2 meters, a stronger spring is debug. In less than a meter a weaker spring should be used!


Due to differences in the shape of the ejector, the ejection window and other factors can be determined with this method is not always 100% correct result. In any case, the differences between different strength springs and different ammunition can be seen. Also you can see here also worn out or broken springs!

Life of the spring

Over the life (number of shots) of a shutter spring, there are many details. So originally shot 1000-1500 were noted, but with today's materials more shots are possible in any case. The uppermost limit should take about 5000 shots!

Measure the recoil spring

With our new measuring device, you can determine the actual recoil spring value. They recognize wear and thus can significantly improve the function of your 1911s:   --> recoil spring gauge NEW!

Recoil Buffer (recoil buffer)

Recoil Buffer (Shok buffs), such as those offered by 1911-TOOLS.COM, Ed Brown and Wilson should dampen the hard knocks, which act in completely swamped spring to the frame.
For this purpose, the tailor-buffers are pushed onto the spring guide rod. It decreases ev. The way the slide backwards running to the thickness of the buffer (2mm or 1/10 ").
It is possible that changes through the use of a buffer, the ejection behavior (throwing direction / area) of the sleeve!
A 100% protection of the frame when using a weak spring does not offer this buffer. It is definitely better to use together with the buffer, the correct spring!

Hammer spring (Mainspring)

A reduced hammer spring (eg 19, 17 or 16 instead of 23 lbs.) Reduces the pressure of the jack hammer on the sear and changes (reduced) by the trigger weight.
At the same time, the resistance is reduced, which carries the hammer at the running back of the carriage. By installing such a spring can ev. change the behavior of the ejector sleeve!

Our tip ...

... before you order now equal a strong spring, check whether the existing spring but is not worn out and you just another factory spring need!

Spacers for the trigger - sear-shims, 4er, (Teflon - PTFE)

Commitment:

- the pressure of the sear spring on the lower left surface of the sear causes
  the sear to be pushed to the right and then fully flush against the frame wall!

- even well oiled the sear is "slowed down" by the large contact surface ...

- by using a PTFE sear shims, the contact area is reduced and the resistance
  is virtually eliminated!

--> 4 pack Teflon - PTFE spacers

original Arkansas stone file for polishing latches, edges, for deburring
and of course suitable for the final touch of all knives!

- use only with oil, never with water!

- Dimensions of the file: approx. 100x13x13 mm

- the Arkansas is an oilstone and has a grain size of about 6000 to 7000!*

- It is suitable for hardened steel (no soft iron or non-ferrous metals!)

- We recommend the use of our FIRST-DOT protect plus gun oil (not protect PTFE!)

*The Arkansas stone is a natural product and may vary in color / marbling / grain size!
