The MOS platform for mounting red dots gets consistent positive feedback. It's straightforward to install and the range of compatible optics footprints is wide. Ergonomics are frequently praised. The G45 frame fits most hand sizes well and the grip angle and texture draw fewer complaints than older Glock generations. Reliability with varied ammunition is cited across nearly every review as a given at this point. The Marksman Barrel draws occasional comments about accuracy improvements. Weight at 24.52 oz loaded is on the heavier end of this size class, which comes up from owners who carry all day. Pricing draws the usual Glock debate. Some see competitors offering similar features for less, others consider the platform's reliability and aftermarket depth to be worth the premium. The broad aftermarket for Glock accessories (holsters, sights, triggers) is consistently listed as a positive. ## Pricing **3 offers available** | Vendor | Price | |--------|-------| | Guns Com | $600.99 | | Gunbuyer Com | $620.00 | | Guns Com | $711.99 | ## Similar Products - [Glock G45 MOS 9mm - Gen 1 Optic-Ready Pistol with Holosun 509T-AG](https://gunsnation.com/p/glock-g45-mos-9mm-gen-1-optic-ready-pistol-with-holosun-509t-ag/UCDSUKu4Z) - [Glock G45 Gen5 MOS 9mm: Precision & Versatility with Optic Ready Slide](https://gunsnation.com/p/glock-g45-gen5-mos-9mm-precision-versatility-with-optic-ready-slide/UCEGGA2Kc) - [Glock G45 Gen5 9mm Compact Pistol - Enhanced Accuracy & Reliability](https://gunsnation.com/p/glock-g45-gen5-9mm-compact-pistol-enhanced-accuracy-reliability/UCDSUKo2h) - [Glock G45 Gen 5 Threaded Barrel 9mm Compact Pistol - 17+1 Capacity](https://gunsnation.com/p/glock-g45-gen-5-threaded-barrel-9mm-compact-pistol-17-1-capacity/UCDSUKpZ8) - [Glock G19 MOS Gen5 Optic-Ready 9mm Compact Pistol - 15+1 Capacity](https://gunsnation.com/p/glock-g19-mos-gen5-optic-ready-9mm-compact-pistol-15-1-capacity/UCDSUKo1a) - [Glock G40 Gen 4 MOS 10mm - Precision Optic-Ready Powerhouse](https://gunsnation.com/p/glock-g40-gen-4-mos-10mm-precision-optic-ready-powerhouse/UCDSUKghS) --- *Data from [GunsNation](https://gunsnation.com)*
