Quarter Circle 10
, makers of the finest pistol caliber AR lowers on the market, including Glock pattern magazine and Colt pattern magazine options. The folks over at QC10 are fantastic to work with and have a lot of very exciting things in development. These are the lowers I reccommend for all AR9 builds because they are visually correct compared to others on the market. The Glock pattern lowers also offer more caliber options than strictly 9mm including 40S&W, 357SIG, 45ACP, 10mm, and 9x25Dillon. They also provide high quality direct blow back bolts for 9mm and 40S&W that are compatible with the Glock mag lowers off the shelf, and barrels in 9mm and 40 to finish out your build.
is a small custom shop in Plano Texas specializing, ironically considering my personal interests, in long range precision rifles and suppressors. The irony comes in to play because I'm a subgun guy, I love PCCs, and for whatever reason David decided to start producing some of the higest quality factory 3 lug 9mm AR barrels I have ever seen. If you're anything like me and have multiple 9mm carbines then it makes the most sense to use 3 lug silencers for quick changes between hosts and you can not go wrong with Shark Precision.
