I don’t have all the parts for this build in hand yet. Most importantly my slide and frame have not shipped and I haven’t picked my ignition set. But I do have a bunch of
My first official step in this build was to assemble the Stan Chen Shooter Installed Magwell by putting in the mainspring assembly (Wilson Combat Pin Set and 17# Wolff Hammer Spring). Big deal, right?
Out of curiosity, without a frame or slide to get to work on, I measured some of the pins and holes of several small parts. The EGW Beavertail Grip Safety is drilled to 0.155″ diameter (spec is 0.156″ + 0.002″) and the Nighthawk Thumb Safety pin is 0.155″ diameter (spec is 0.1555″ – 0.002″) and they fit together perfectly.
The Nighthawk Slide Stop pin is 0.199″ diameter (spec is 0.2005″ – 0.002″). I don’t know, for sure, which barrel link I’ll end up using, but the #3 link in the Wilson Combat Barrel Link Kit has a 0.204″ diameter hole for the slide stop pin (spec is 0.2045″ + 0.001″).
This is probably a good place to point out the value of a pin gage set; they make measuring hole diameters very easy. Some other uses I’m anticipating for them are measuring the frame rail slot width and depth, the slide rail slot width
