Although most modern M1911-style pistols come from the factory with flat mainspring housings, some shooters still prefer the arched style that was standard on military-issue guns for generations. But finding the latter cut with fine checkering to match the frontstrap texturing of higher-end pistols is not easy. Rock River Arms, a longtime supplier of quality M1911 components, comes to the rescue with steel mainspring housings checkered 20, 25 or 30 lines per inch. And not only does the company offer them in both flat and arched styles, it also offers serrated versions and even some fitted with lanyard loops. Price: $40-$45. rockriverarms.com.
