Steiner just dropped a shrunken version of its MPS pistol optic aimed squarely at compact and subcompact carry guns.
The MPS-C rides the RMSc footprint — the same cut found on the Shield RMSc, Holosun EPS Carry, and other small-frame optics — making it a direct play for Shields, Hellcats, P365s, and similar platforms.
The headline feature is the enclosed emitter design. Unlike the exposed-emitter dots that dominate the budget end of the market, the MPS-C’s LED sits protected behind a fully sealed housing with a recessed, shrouded window. That matters on a carry gun that lives in a holster, gets sweated on, and occasionally takes a beating. The Class III hard-anodized aluminum housing with reinforced sidewalls should handle the abuse.
At 1.13 ounces and 1.46 x 1.27 x 1.08 inches, it’s genuinely small. The window comes in at 20x16mm — not cavernous, but adequate for a defensive dot. Steiner specs the reticle at 1.6 MOA, which sits in the sweet spot between a precise aiming reference and a dot you can actually find quickly under stress.
Twelve brightness levels cover the bases: 10 standard day/low-light settings plus two night-vision compatible modes. Battery life is rated at 46,125 hours on the lowest setting and 13,000 hours at mid-brightness off a single CR1632. Shake-awake and a user-selectable 13-hour auto-off round out the power management features.
The elephant in the room is price. At $574.99 MSRP, the MPS-C is competing against the Holosun EPS Carry ($330-ish street) and the Sig Romeo-X Compact, both of which offer enclosed emitter designs at lower price points. Steiner’s argument is military/LE pedigree and build quality — the original MPS has real-world credibility with serious users. Whether that justifies the premium for a carry optic is a conversation worth having.
