Perfect addition for my SIG pistol. Easy to install and very functional once sighted in.

Went out on a limb to try one. Ended up with the ST and an XL. Quality optic with One of the best warranties in the industry from Vortex. Can't go wrong. Super clear glass. Already have SROs and 507 comp and 507c.

After 6 months, this seems to be a quality product. Fit my weapon well. Same quality I expect from Vortex

Sits well on my Glock 19x Mos. Seems very durable and good battery life.

Love the Optic got one for my CCW and my work gun a year later. Battery life is short on high though if you are walking around all day.
