XGA HS507K vs. HS507C Price & Feature Comparison ($119 vs. $129)
When upgrading your handgun with an optics-ready red dot sight, choosing between subcompact and full-size options is one of the most important decisions you will make. XGA offers two feature-packed optical solutions designed for different slide dimensions and holster profiles:
XGA HS507K ($119.00): Built for slimline, subcompact everyday carry (EDC) handguns.
XGA HS507C ($129.00): Built for full-size, compact Duty, and Competition pistols.
In this direct comparison, we breakdown their key differences, footprint compatibility, target applications, and why both optics offer unmatched durability for their price points.

Footprint & Mounting Compatibility
The primary distinction between these two optics lies in their mounting geometry:
XGA HS507K ($119.00): Uses the native modified Shield RMSc (K-footprint). It mounts flush onto slim slides without adapter plates, preventing overhang and snagging during quick draw from concealed holsters.
XGA HS507C ($129.00): Uses the industry-standard RMR footprint, featuring a wider window for maximum target acquisition on duty, home defense, or competition handguns.
Structural Durability: Hard Impact Wood Block Test
Despite the $10 price difference, both optics are constructed with high-strength 7075-T6 aircraft aluminum housing to resist violent slide recoil.
In rigorous factory stress testing, both the XGA HS507K and XGA HS507C undergo direct hard-impact testing—including being struck repeatedly against solid wood blocks—without losing zero retention or reticle clarity.
“Whether you choose the compact K-footprint $119 HS507K or the full-size RMR $129 HS507C, you get battle-ready zero stability and hard-impact durability across both platforms.”
Which Optic Should You Choose?
Choose the XGA HS507K ($119.00) if you carry a subcompact firearm daily and require a low-profile, flush-fit red dot sight.
Choose the XGA HS507C ($129.00) if you shoot a full-size or duty pistol where a larger optical window speeds up target transition.
