HD-130 Retro ignition set

Tool steel ignition set featuring Retro bobbed spur hammer
My ignition sets consist of hammer, sear and disconnector and are manufactured from top grade tool steel to provide precise fit and reliable, consistent function under the most demanding conditions. Each part is wire EDM'd and CNC machined for a precise +/- .0005" tolerance, heat treated to Rc 53 - 56, then honed and mirror polished to give Extreme Service in your pistol.

The Retro hammers features a bobbed spur that is machine radiused and undercut below the spur to be "bite-free" when used with an A-1 style grip safety or of course, a beavertail. These hammers are also slightly narrowed to avoid unwanted contact with the slide or ejector. The spur has deep serrations to help you keep the hammer under control and all exterior corners are CNC machine beveled to minimize snagging and abrasion. I have used the Retro hammer in combination with many beavertail grip safetys. Most interact with with no modifications, hovever some beavertails may require that a small amount equivalent to the last two serrations be ground off to let the hammer completely cock.

The sear is shaped to minimize excess material, reducing weight. The standard sear nose features a polished primary angle and breakaway angle. The TR sear uses a .404" radius with an escape angle. Fully polished surfaces mean smooth operation in the points of contact between the disconnector, sear and hammer. While I don't care to use the term "drop-in" and all that it implies, these ignition sets are prepped and polished and many folks install these parts that way with satisfactory results. 
 
Ignition Sets available in either "in the white" carbon steel, stainless steel, or coated with black IonBOND DLC with either the traditional two angle sear or the "TR" True Radius sear  with tool steel disconnector.
 
Again, I do not advertise my parts as drop-in. There are just too many variables in dimensions and tolerances between frames and the associated parts involved to really make that claim and it be true. You should be able to obtain a satisfactory trigger pull with these parts but any or all of these standard jobs that are involved in a 1911 trigger job are to be expected and must be dealt with satisfactorily. This includes checking &adjusting the parallelism of pin holes and their squareness to the frame, checking & adjusting the diameter of sear and hammer pins and their fit to those parts, checking and adjusting for even bearing contact on both hammer hooks with sear nose, checking and adjusting for adequate engagement in the depth of sear nose to hammer hooks, adjusting correct tension setting of sear spring leaves, checking for adequate take-up resulting in correct operation of captive half-cock notch and any adjustment necessary to ensure it’s correct operation, correct operation and adjustment of over travel stop, correct operation and re-fitting of thumb safety, correct operation and re-fitting of grip safety, correct operation and adjustment of any firing pin blocking safety system.
