This modification is more than just beautiful. It can protect your crown from damage and any time you machine a precision barrel crown, your accuracy will most likely improve. We prefer to machine a 30 degree crown. We feel it looks the best and have had great results with it. We will also do an 11 and 45 degree crown.
The 4 corners of the frame are precision micro welded on 2 bearing surfaces using small filler material and unparalleled heat control and are machined to meet the slide's dimensions. Micro welding with small filler and more centralized heat helps eliminate the chances of warping the frame when compared to conventional TIG welding.
Our carry bevel is a mix of machine and hand work on key external surfaces of the firearm. We rework the contours of the frame and slide to eliminate all sharp corners to ensure a snag free draw.
Our large machined mag well bevel opens up the standard mag well greatly ensuring quick magazine changes.
Precision machined in the Novak style with our custom ground undersized dovetail cutters to ensure the dovetail is not machined oversized. The dovetail is machined to the individual sight's dimension to ensure a nice fit.
The slide and frame rounds along with the small parts are aluminum oxide blasted. The frame and slide flats are hand sanded to a beautiful brush polished look. We offer a couple levels of bluing. Please call or email to get an accurate price.
Precision machined on the mill, the ejection port is lowered to .475 from the slide bottom and a live round relief cut is machined in the front of the port. The slide is then tilted 30 degrees and the port flair is precision machined with a large ball end mill for the perfect flair. The bottom of the ejection port is then beveled.
Our grip safety fit starts at the mill. We tram the thumb safety hole on the rotary table and machine the tangs to a perfect radius. The frame tangs are milled to slightly over a .250 radius and are fit the rest of the way by hand. We prefer to use .250 radius grip safeties with the exception of Springfield Armory frames which tend to work best with .220 radius safeties. We are big fans of EGW .245 and John Harrison .240 radius safeties for use with frames that have over cut .250 radius frame tangs from the factory. Parts included (refinishing charges are separate)
First the slide is leveled on its side and indicated. If a slide has a low spot in the middle that is too great, the sections before and after the ejection port will be done separately. Next, a flat approximately .300 thousandths wide is machined on the top of the slide and serrations, usually around 40LPI are machined in various patterns. Our basic flat top and serration is $175. The double arrow pattern shown is $200
Front strap checkering. First the front strap is measured to ensure it is thick enough so the serration cuts don't break through the front strap. A minimum of .065-.075 thousandths of an inch is required. Then the front strap radius is trued to eliminate any low spots that will create flat or lowered checkering points and the under cut for the trigger guard is machined in at the same time. Then the horizontal and vertical serrations are machined in at 20, 25 or 30 lines per inch
We love Harrison Design parts at Evolution Armory. Service includes an oversized fit trigger using the color and length of your choosing, the Harrison Design 120 ignition kit in standard or true radius form, a new standard or reduced power main spring, and a Colt sear spring. Substitutions can be made as long as quality parts are used. We will not accept any action work on Para pistols of any model.
The Stan Chen Generation II magwell is truly a game changer. It allows for a huge magwell opening without adding any additional grip length and there is no welding necessary as this is a one piece design. It is available in stainless or carbon steel and in your choice of blank, 30, 25 or 20LPI. This magwell is becoming a fast favorite at the shop. Another great innovation marketed by Stan Chen, who was gracious enough to allow us to be an authorized installer of this truly innovative product.
This simple embellishment can really add some character to the slide and give it a finished look. Available in a 60 degree V groove or a ball cut.
These elegant hand filed serrations add a custom touch to the gun by continuing the rear sight serrations to the slide and also help reduce glare.
Are you a left handed shooter who has an issue pressing in the slide stop pin with your support hand, or just someone who dislikes the look of the slide stop pin sticking far out of the frame? This mod is tasteful and practical at the same time. We machine a bevel into the slide stop hole in the frame, shorten the pin, and profile the edge to allow for normal insertion of the pin into the barrel link. Refinishing charges apply.
A match grade barrel is the best way to ring out your accuracy potential. We prefer Kart gunsmith fit national match barrels here at Evolution Armory but will install any top quality barrel of your choice. Install includes the barrel, an EGW bushing, link and link pin sized right for your pistol. Prices start at $450 for a Kart standard profile barrel. Ramped barrel machining is an additional 80 dollars and refinishing costs for a ramped barrel install will apply. An additional fee may be charged for non Kart barrels, depending on the cost of the barrel.
This modification gives the slide a look like a Browning Hi Power and provides some grip to perform press checks without having to machine cocking serrations on the front of the slide. Minimum slide thickness between the outer wall of the slide and the lowest part of the barrel bushing slot must be met or the modification can not be performed. Not all slides will be able to have this modification, especially if front cocking serrations are already present. Refinishing is required and separate.
