We have shops in NC and FL.

We provide DLC and PVD coating services. Shops in NC and FL.

We used them several years ago. Out of the blue they told us that they were no longer going to do firearms finishing. They did good work for the most part, although, some pieces that came back had to be redone, which added considerably to the turn around time...and to the labor cost. Without have to return a piece to have it finished a second time, turn around was several months.

The Kuhnhausen books are good reference books with a lot of information. We've had a set since day one. There is a book currently being written by an engineering professor at UNC. Besides building pistols and shooting them in competitions, he is a firearms researcher. His book - first in a series - will focus on the 1911 and is being written in collaboration with well known gunsmiths, gunsmithing instructors, and firearms manufacturers. In addition to being a reference work like the Kuhnhausen books, his goal is to provide a step-by-step build manual, with each step showing several methods of accomplishing the task at hand, tool and parts lists, etc. We believe it is due out around January 2019. If you have any interest, drop us a line and we'll get you more info. Deep River Customs info@deeprivercustoms.com

We do nitride finishes on stainless guns that we build or refinish for customers all the time. One thing to be aware of is a nitride finish can make it difficult to get the gun back together if the fit was tight to begin with. Nitride finishes are in the 20-50 micron range (~.0008"-.002"). Titanium and aluminum we only coat with DLC or one of the many PVD, e.g. TiN, coatings available, depending on the part and customers' color preference. Titanium generally isn't an issue with these coatings. The aluminum parts have to be good quality aluminum, otherwise they'll vaporize in the chamber and cause a big cleanup headache. We mostly do frames, triggers, MSH, and the occasional grip in DLC/PVD on Aluminum.

From what we've been told by the PVD/DLC processor we work with is that the temps are 300-400 F, so warping shouldn't be a problem.

EGW and Nighthawk also sell the .250" guide rods needed to allow use of flat wire springs.
