What is the BROWNELLS - RMR Slide, Shield Optic Cut for Glock 43, Black Nitride?

The Brownells RMSC Cut Slide for Glock® 43 enables you to install a Red Dot with the RMSC footprint on your pocket Glock®. It offers all the benefits of our "Front Cut" slide for Glock® 43, including forward slide serrations that give you extra leverage in manipulating G43's slide against its stiff recoil spring. The cutout on top of the slide behind the ejection port accepts a Shield Sights RMS or other red dot that fits the RMSC mounting footprint. The RMS Cut Slide for Glock® 43 also comes with a factory rear sight dovetail and slot for the front sight tenon. They will accept both factory plastic sights and any aftermarket sights that fit the factory cuts, enabling you to co-witness "iron" sights with the red dot for backup.

NOTE: Requires 6-40 Size screws which Brownells does not currently carry.

Compatible Red Dots:
-Shield RMSC
-Vortex CCW Defender
-Holosun 507K & 508K
-Holosun EPS
-Sig Romeo Zero Elite
-Swampfox Sentinel
-Springfield Armory WASP
-Riton MPRD

Features:

  • Machined from heat-treated & hardened 17-4 stainless steel billet
  • Hard, wear-resistant matte black Nitride finish
  • Internal dimensions identical to factory slide
  • Includes Factory rear sight dovetail & front sight tenon cut
  • Slide only - no internal parts (see Gun Tech Note below)

Our RMS Cut Slide gives you more grasping surface on your Glock® 43 by adding deep-cut serrations up front. This is a big help when making a quick press check of the chamber. Both the front and rear serrations are cut to the same depth as the factory grooves - so there's no compromise of overall slide strength. Crisp 90-degree edges on the grooves give you excellent purchase for chambering a round on the first try.

Brownells Gun Tech™ Note: The Shield Sights RMSC Cut Slide for Glock® 43 consists of the bare slide only. You will need to retain your pistol's existing barrel (or an aftermarket upgrade) and recoil guide / spring assembly, extractor, extractor depressor & spring assembly, and rear coverplate. The G43 slide does not require a firing pin channel liner.

What Reviewers Are Saying
Product Quality
55%
Reviewers express concern about the overall quality of the slide, particularly noting issues with internal tolerances that lead to jamming and failures to feed in various Glock frames. Many users emphasize a lack of consistency in the manufacturing process, leading to mixed performance experiences.
Fitment and Installation
45%
Many users report that the slide fits well on their Glock frames and is easy to install. Comments highlight successful use of factory internals and indicate the slide's aesthetic appeal, but some also mention issues with fit, such as loose screws and alignment problems.
Quality Control Issues
60%
A recurring theme is dissatisfaction with quality control, particularly indicated by rust in mounting holes and inconsistencies in screw sizing. Many reviewers suggest that the product may have been shipped without proper inspection, impacting user confidence.
Customer Service
40%
Users appreciate the responsiveness and help provided by customer service when issues arose, especially regarding replacements and guidance on defects. However, this is seen as a necessary response to the mentioned quality issues rather than a benefit of the product itself.
Performance Issues
45%
Several reviews indicate significant performance issues, including failure to extract and feed, light primer strikes, and failure to reset the trigger. These problems undermine trust in the product's reliability, particularly for those relying on it for serious use.
Finish and Aesthetic Concerns
50%
While many users commend the nitride finish, there are notable concerns about discoloration and rust around the mounting holes, detracting from the product's overall presentation. Cleanliness upon arrival also varies, impacting first impressions.

Great product
Ive had the slide over a year now. Purchased one of Brownells slides rather than sending mine off to be milled and coated. No problems switching from a 43, 43X or a 48. Ive used Glock barrels and a True Precision barrel now stays in it. Purchased a SCT frame on sale a few month later and have a complete gun. It felt a little gritty at first when working the slide. I thought i cleaned and lubed it well prior to shooting. One or two mags of ammo cured that. Wouldn't hesitate buying another.
Would you recommend this? Yes, I would recommend to a friend

Great optoon to milling your factory slide
Fits and looks great. First time fully assembling a stripped slide. Wasn’t that hard. Hardest part was getting the spring caps on the firing pin assembly.

Seems good so far.
A EPS Carry fit right on it. Seems well made, although i'm no gunsmith.

Great fit, great price
Everything fit together perfectly. Used the factory Glock internals and paired it with a holosun 507k.

Perfect!
Easy swap out... everything fit like a glove. For a little more than the cost of milling your slide, you can have a backup "non optic" slide as well.
