If you're tired of brittle factory MIM struts or just want to squeeze a little more performance out of your 1911 or 2011, this EGW titanium hammer strut is one of those small parts that punches well above its weight. EGW machines it from solid titanium, which is noticeably lighter than steel while staying plenty tough for the job. Less reciprocating mass in the fire control group means a faster lock time, which is the tiny gap between the sear releasing the hammer and the firing pin hitting the primer. Shooters chasing precision and competition shooters care about that, and it doesn't hurt the rest of us either.
The design itself is worth pointing out. EGW made this strut a touch longer than standard, which keeps the hammer under mainspring tension even when it's all the way down and eliminates free play. The improved radius is shaped to keep the strut from rubbing on the sear spring, which protects your trigger feel, and it also clears most grip safeties without a fight. The end result is a stronger, more consistent hammer strike paired with a smoother pull.
Fit-wise, this is the X-long version sized for Government, Commander, and Officer length 1911s, and it works across all calibers. It also plays nicely in 2011 builds. Worth knowing up front: Sig Sauer 1911s often use proprietary mainspring housing and hammer geometry, so a standard-pattern strut like this one usually won't fit those without issues.
This is a single titanium hammer strut. It does not include a strut pin, so if you're swapping into a fresh hammer you'll want to grab a pin too. Installation involves pinning the strut to the hammer, and a lot of folks stake the pin so it doesn't wander off during disassembly. It's a straightforward job for anyone comfortable detail-stripping a 1911, but if you're new to the back end of these guns, a gunsmith can knock it out quickly. Overall length comes in at 2.221 inches, and like the rest of EGW's parts, it's made in the USA.
The hammer strut sits between the hammer and the mainspring inside the mainspring housing, transferring spring force to drive the hammer. When you cock the hammer it compresses the mainspring, and when the sear releases, that stored energy powers the hammer forward into the firing pin. A good strut keeps the hammer under proper tension and helps deliver a consistent, reliable strike.
Titanium is significantly lighter than steel while still being strong, which cuts down the reciprocating mass in your fire control group. That reduction translates to a faster lock time, which precision and competition shooters value, plus a smoother trigger feel. It's also a big step up from the brittle MIM parts found in many factory guns.
This X-long strut is sized for Government, Commander, and Officer length 1911s and works across all calibers, and it's also a fit for 2011 builds. Heads up though: Sig Sauer 1911s frequently use proprietary mainspring housing and hammer geometry, so a standard-pattern strut like this typically won't run correctly in most of those designs. When in doubt, check your specific model.
No, this is just the titanium hammer strut by itself. If you're installing it into a new hammer, you'll need to pick up a hammer strut pin separately. Reusing the pin from an old hammer can be hit or miss, so a fresh pin is usually the easier route.
If you're comfortable detail-stripping a 1911, it's a manageable job. You pin the strut to the hammer and many people stake the pin so it doesn't fall out during future disassembly, though when properly installed the pin is captured in the gun. If you've never been inside the fire control group before, having a gunsmith handle it is a quick and worry-free option.
