Glock handguns are popular—Yes, we realize that’s one of the biggest understatements ever posted to this site—and with this popularity comes a whole subset of companies ready to offer aftermarket parts for them. One of those companies is Suarez International, and one of Suarez’s latest products is its new Supermatch SI-43 Glock 43 slide.

Suarez says it built the SI-43 Glock 43 slide for the shooter who wants the benefits of its Supermatch slide, but doesn’t want to run a red Trijicon RMR or cut the slide to accept another red dot. Made from 17-4 aerospace stainless steel, it features ergonomically angled and shaped serrations; tighter tolerances for enhanced accuracy; ejection port lowered by .100″; integral “blood groove” design and a Suarez logo.

All of these features combine to “create a slide that is deadly accurate, combat-ergonomic, as well as aesthetically pleasing,” Suarez claims in the product listing.

The Suarez Supermatch SI-43 slide for the Glock 43 comes in either a black melonite or NP3 coating. MSRP for the former is $239.99, while the latter will raise the price to $259.99. Details are below.
