Reviews
Just like the 43x slide, but longger...
Fit and finish are perfect, and really does tame the recoil on these micro compacts. The slide serrations are fantastic too, feel like that is an underappreciated feature when swapping to Arc!
Highly recommend! stop spending almost the same for a barrel + comp that makes your pistol ammo picky and cumbersome.. #ReactorGang
This is hands down the best ready to run, drop in, custom ported Glock setups there is. Sure you can send in your stock slide and barrel and wait for weeks-months, OR you can buy this setup that’s ready to drop in and head to the range. I paid for my kit with my own hard earned money as well and it was well worth it after you factor in the slide cost, barrel cost, and milling/ machining work to port and optic cut, plus the lead times. Patch is also AMAZING. Saving up for a slide for my G45.
The fit and finish are fantastic and the aesthetics are amazing! It also really works to help reduce recoil. I love it!
There is no better quality provider for clones than Arc. Whenever someone visits my store and mentions wanting a “Gucci Glock,” I always recommend Arc. I own several Glocks, but my preferred models are the 17, 19, and 48, which I use exclusively. When teaching my classes, students often ask where I obtain my slide and barrel, assuming they are from Agency Arms or Noveske. However, in terms of quality and attention to detail, Arc surpasses those brands. These are now the only Glocks I run.
I want to thank Patch and the ARC Division team who worked with me on this G48 build. Absolutely fantastic craftsmanship and runs 9 like a dream! Eagerly awaiting my 43x
