Recoil Spring FAQ

The recoil spring in a 1911 pistol is an important part of the puzzle of overall autoloader reliability.  The primary purpose of the recoil spring is to strip a cartridge from the magazine during the feeding process and secondly, to protect the frame from excess slide battering during operation.

Our recoil springs are carefully wound and heat treated in the USA of the finest ordnance-spec music wire to give you long-lasting durability and resistance to heat and deformation over time.  They have been thoroughly tested and will maintain a consistent spring weight during long-term use.

Even though Wilson Combat recoil springs are the best springs you can buy, we recommend changing your recoil springs at regular intervals to optimize your pistol’s performance and enhance reliability.

  • If you start getting failures to return to battery while feeding, it may be an indication that your recoil spring is losing some of its overall length. Typically, compact pistols will require more frequent length recoil spring changes than standard pistols.
  • If your Shok-Buff recoil buffer is becoming torn within a few hundred rounds after installation, that is also evidence that your recoil spring is ready to be replaced.
  • Any easy way to check for a worn spring is to compare your recoil spring versus a new spring of the same weight and brand.  If your spring has lost approximately one-half an inch of overall length, it is time to replace your spring.  To ensure this you should always have extra recoil springs of your desired weight(s) on hand.
  • Any time you buy a second-hand or older 1911 pistol, it is a good idea to bring all unknown poundage springs back to factory spec for reliable operation.  New, quality springs are a cheap insurance policy against malfunctions and pistol damage.
  • If your ejection or extraction pattern suddenly changes, you may have a weakened recoil spring.
  • The proper recoil spring weight for a 1911 pistol is dependent on the caliber, length of the barrel, and the tension of the hammer spring.
  • It is advised to tune your spring weights based on the type of loads you prefer to shoot most often.  If you shoot mostly lighter loadings, use weights at the lower of the spectrum; conversely if you prefer heavier or +P loads, try heavier springs.
  • For all-around reliability try spring weights in the median of the recommended spectrum.
  • If your pistol fails to lock back on the last round after installing a new recoil spring, you may need to try a lighter weight spring.
  • Wilson Combat recommended spring weight ranges are as follows:

 

Caliber/Barrel length Recommended Recoil Spring Weight Range
.45 ACP 5” 15-18.5#
.45 ACP 4.25” 17-20#
.45 ACP 4” 18-22#
9mm 5” 10-12#
9mm 4” 11-13#
.38 Super 5” 13-16#
10mm 5” 18.5-2

 

When replacing your pistol’s recoil spring it is important to remember to change your firing pin spring at the same time.

  • The firing pin spring is one of the most important springs in your 1911 pistol.
  • A weak or broken firing pin spring can cause a failure to fire and can also reduce the drop-safe qualities of your pistol.

Extractor FAQ

The extractor is a critical part of 1911 reliability.  The 1911 extractor is a brilliant John Browning design that is easy for the user to adjust and maintain. It provides its own tension and can be tuned to compensate for varying tolerances of different firearms.  The main downside to the 1911 extractor is that it often requires fitting or adjustment for perfect function.

The sole function of the extractor is to remove an empty case from the chamber during the firing cycle, hold it in position for the ejector to strike the case head, and deflect the empty case out of the ejection port to make way for a fresh round.  This sounds simple, but the shape and spring tension of the extractor influences the entire firing stroke; too much extractor tension can cause failures to feed and too little can cause failures to extract.

  • If you have failures of an empty case to extract, you may need to adjust or replace your extractor.
  • If you have failures to eject an empty on the last round, you may need to adjust or replace your extractor.
  • If you have erratic ejection of fired cases, you may need to adjust your extractor or try an oversize firing pin stop that prevents excessive extractor movement in its tunnel.
  • If you have failures to chamber, you may have too much extractor tension.
  • A good live fire extractor test is to fire your 1911 with the magazine removed a minimum of 5 times; if the empty consistently ejects each time without a magazine in place, you likely have sufficient tension on your extractor.

With the slide taken off the frame and the barrel removed, slip the rim of a LOADED cartridge under the extractor hook and position it so that the extractor is gripping the case at the center line. To verify this use the barrel as a guide and move it into battery over the round. You should now be able to lightly shake the slide in any direction, without the cartridge falling off. The nose of the bullet should dip slightly.  When using an empty case to verify extractor tension, the case mouth should sit straight at 90 degrees to the breechface. If this test is unsuccessful, you will need to adjust the tension.

For tension adjustment, place approx. 1/2″ of the tip of the extractor into the extractor channel and apply just enough pressure to slightly bend the extractor. Be careful, a little goes a long way!

Do not put more tension than needed to perform this simple test — too much tension will result in feeding malfunctions whereas too little tension can cause failure to extract and/or erratic ejection.

1911 Sight FAQ

Wilson Combat handguns with tritium night sights exclusively use tritium lamps from the best domestic manufacturer– Trijicon.

Since the glow from your night sights is actually a by-product of harmless radioactive tritium decay, most sights have a brightness of less than 10 years.  We will service our night sights for seven years from the build date of the firearm (not the purchase date).  If at any time your sight(s) goes out or becomes unusable within that timeframe we will replace them.  If your pistol is older than seven years old you have various options.  We can replace your entire sights at standard gunsmithing rates and turnaround, or you can return your slide to Trijicon to replace just the tritium lamps for a nominal fee and 2 week turnaround ($18 per lamp as of 1-1-2013).

We build guns with a variety of front sight heights so it would be impossible to say what front sight your particular pistol needs without inspecting it.  

Most pistols with combat-style, fixed rear sights will use between .150″-.200″ tall depending on barrel length, barrel fit, caliber, and height of the rear sight.

Most guns with fully-adjustable rear sights (like our low-mount adjustable rear sight that is used on the Classic model) will use a .170″ front.

The best way is to either send us your slide or simply measure the height of the sight with a depth micrometer from the top of the sight to the top of the base.

Here are the heights we offer:

http://shopwilsoncombat.com/Front-Sights/departments/342/

Most front sights will require gunsmith installation.

For precision shooting, align the top of the front sight post and the top edge of the rear sight. The POI (Point of Impact) should be close to the tip of the front sight. When shooting groups, shooting at extended range, or shooting at a small target, you should ignore the bead/dot. Don’t try and align the bead/dot with the u-notch. The u-notch is just an aperture for eye to look through.

For snap shooting, shooting at close range, shooting in dim light, or shooting at HIGH speeds the gold bead is used to maintain focus on the front sight and help you find it.

Every Wilson Combat handgun ships with a test target shot by a professional shooter that establishes the correct windage and elevation (Point of Impact) for every gun we build. Most handguns are set up to shoot approximately 1″ high at 15 yards.  This ensures that most shooters have an effective point of impact with a dead on hold (Point of Aim) out to 50 yards with service ammunition.

Armor-Tuff® and Finishes FAQ

ARMOR-TUFF® Protective Firearms Finish was developed specifically for firearms use to provide a non-reflective tactical surface finish with optimum corrosion protection, abrasion resistance and enhanced lubricity. The low curing temperature prevents parts damage or warping during the finishing process. A firearm finished with ARMOR-TUFF® has the most durable, chemical and heat resistant, thermally-cured firearm finish available.

Before a firearm is coated with ARMOR-TUFF® the firearm is thoroughly sand blasted with fine grit media, then carefully dehorned and every surface prepared by hand. Every carbon steel firearm is phosphate parkerized before we apply the final finish to form a bonding surface for ARMOR-TUFF® that increases durability and corrosion resistance.

A highly trained finish technician then sprays the ARMOR-TUFF® coating on the firearm before it is thermally cured. After the firearm is re-assembled it is given a thorough inspection to ensure the finish meets our highest standard of quality and ensure your firearms reliability.

ARMOR-TUFF® has a very attractive, non-reflective matte surface finish that looks very similar to an ultra-fine sandblast blue job. ARMOR-TUFF® is available in matte black, matte OD green, matte grey and matte tan. We can also do various combinations of these colors. Check our gallery (Coming Soon) for examples of different color combinations. ARMOR-TUFF® can also be applied to Stainless Steel and anodized aluminum.

ARMOR-TUFF®, when applied to parkerized carbon steel, will pass the test procedures for salt water spray testing without corrosion for over 3000 hours! Properly ARMOR-TUFF® coated surfaces will not rust when subjected to normal firearm use.

ARMOR-TUFF® provides excellent anti-friction characteristics over typical firearms finishes. We do, however, still recommend a quality lubricant like ULTIMA LUBE II be used on contact surfaces.

ARMOR-TUFF® will meet or exceed 24-hour immersion requirements in the following fluids: aviation gasoline, hydraulic fluid, jet fuel, lubricating oils, paint removers, trichloroethylene, hydrochloric acids, hydrogen peroxide, gunpowder solvents, common gun lubricants, strong bases, and numerous other chemicals.

ARMOR-TUFF® will withstand exposure to temperature extremes of +1000 degrees F to -250 degrees F.

ARMOR-TUFF® has a nominal thickness of between .0003″ and .0009″ unless a thicker coating is desired, such as on high-wear areas like a pistol grip safety or frontstrap. The thin coating characteristics of less than one thousandth of an inch allow easy re-assembly of precision fitted parts.

ARMOR-TUFF® is applied at our finishing facility in Berryville, Arkansas, under the strictest quality control standards by Master finishing technicians and gunsmiths with years of experience.

We also offer other finishes.

Stainless Steel is not a coating but actual firearms-grade stainless alloy in a variety of finish levels. Stainless Steel can be finished in a non-reflective, bead-blasted matte gray or a hand-finished brushed, satin silver finish. A Stainless Steel frame and black or blued slide is a classic 1911 color combination. Since the finish is based on the surface preparation of the steel, Stainless is easier to refinish than a coated pistol. Stainless Steel can be finished with ARMOR-TUFF® to lower a firearms reflective signature.

Aluminum Anodizing – A process of hardening and finishing lightweight aluminum alloy in an electrically charged bath to greatly enhance strength and service life over untreated alloy. All Wilson Combat lightweight 1911 pistols and AR-15 rifles are Mil-Spec “hard” anodized as part of the custom-build process prior to ARMOR TUFF® finishing in the color of your choice.

Bluing – Conventional hot salts bluing gives a deep black finish that is applied by boiling finished carbon steel parts in a caustic salt solution. Our hand-finished deluxe blue is applied to our polished carbon steel for a truly custom look.

Case Color Hardening – A special hardening process that can be applied to a carbon steel frame or carbon steel small parts to give the ultimate in a traditional, high-end bespoke look. The mottled rainbow of blues and browns of authentic Case Color is a rare and appealing high-end finish for your dream custom 1911. Pricing and details on request.
