Description
When you're building a 1911 from parts or freshening up one that's seen a lot of range time, the little stuff matters just as much as the big stuff. The Wilson Combat 315S pin set gives you the complete run of pins needed to construct, rebuild, or recondition a 1911-style auto pistol, all in one bag so you're not hunting down individual parts one at a time. It's the kind of small investment that saves you a headache down the road.
What Makes the 315S Pin Set Worth Having on the Bench
These pins are machined from high grade stainless steel and heat treated to the proper hardness, which is exactly what you want in a wear part that takes a beating from repeated cycling. Stainless is a natural pick if you're working on a stainless or bright finish 1911, since the silver look matches the rest of your gun instead of standing out. Folks who've swapped these in on Springfield frames and other builds consistently mention the fit is clean and the parts hold up.
Fitment and a Quick Note Before You Start
The 315S set covers 1911 frame sizes A through O, so it's a broad fit across the platform. Keep in mind these are quality parts that may need minor fitting for a perfect result, which is normal territory for anyone assembling or reconditioning a 1911. One tip worth passing along: the hammer strut pin is a press fit, so a simple pin guide or punch makes tapping it in a clean, easy job.
Pair this set with a good spring kit and you've got the small hardware side of a 1911 refresh handled. Whether you're a home gunsmith putting a project together or just replacing worn pins to keep an old workhorse running right, the 315S is a dependable, no-drama choice from a brand that lives and breathes the 1911.

Frequently Asked Questions
What does the Wilson Combat 315S pin set include?
It's a complete set covering the pins you need to build, rebuild, or recondition a 1911. That includes the barrel link, sear, ejector, hammer, and hammer strut pins, plus the mainspring cap pin, housing pin, housing cap pin, housing pin retainer, and the safety lock plunger pin. Everything comes packaged together so you're not chasing down single parts.
Will the 315S pin set fit my 1911?
The set is designed to fit 1911 frame sizes A through O, so it covers a wide range of the platform including full size builds. As with most 1911 internals, some pins may need minor fitting for a perfect result. If you have a standard 1911-style auto, you're generally in good shape.
Are these pins stainless to match a stainless 1911?
Yes. These are stainless steel with a silver finish, which is a great match if your 1911 has a stainless or bright finish. Owners often grab this set specifically because the factory gun came with a mix of finishes and they wanted every pin to match.
Is the hammer strut pin hard to install?
The hammer strut pin is a press fit rather than a slip fit, so it takes a light tap to seat. A simple pin guide or punch holds it in place and makes the job quick and clean. The rest of the pins install like standard 1911 hardware.
