This review of the SMS Trinity laser highlights its robust build quality, impressive IR illuminator brightness, and IPX8 waterproofing. The instructor, with over a month of testing and thousands of rounds, details its performance, including its durability under impact and its effectiveness with night vision. While it holds zero through standard use and recoil, a significant impact from a hammer caused a minor shift, though still considered acceptable for its intended purpose.

Quick Summary

The SMS Trinity laser is a highly durable and waterproof (IPX8) tactical accessory, featuring an exceptionally bright IR illuminator suitable for night vision use. After extensive testing, including thousands of rounds and simulated impacts, it demonstrates excellent zero retention for its intended purpose of target acquisition on body-sized targets.

Frequently Asked Questions

What is the SMS Trinity laser's waterproofing rating?

The SMS Trinity laser has an IPX8 waterproofing rating, meaning it can withstand submersion in water. The reviewer tested this by leaving it submerged overnight, and it functioned perfectly afterward with no water ingress.

How durable is the SMS Trinity laser under impact?

The SMS Trinity is very durable. While it held zero through standard use and recoil, a significant impact from a hammer caused a 2 MOA shift. This is considered acceptable for a laser sight intended for body-sized targets.

How bright is the IR illuminator on the SMS Trinity?

The IR illuminator on the SMS Trinity is exceptionally bright, often requiring lower power settings even in complete darkness when used with night vision. It's so bright it can 'blow out' sensitive camera sensors.

What are the advantages of the SMS Trinity over previous models like the HFXC?

The Trinity features a throw lever for IR beam adjustment, improved waterproofing (IPX8), and recessed turrets that are less prone to zero shift from impacts. Its overall rigidity and build quality are also significantly improved.

Is the SMS Trinity laser worth its $350 price point?

Yes, for its price point of around $350, the SMS Trinity is considered the best on the market for civilian use. It offers excellent performance, durability, and features that rival much more expensive units.
