Question: Does this fit the Sigma .40, and is all mounting hardware included?
Document: This little laser is the perfect fit for the sigma 9mm and sw40. stays accurate after 100s and 100s rounds!!! You can hardly even see the unit when it is installed. Very happy with this purchase.
I wanted a nice unobtrusive underbarrel laser for my .40 and this one is great. Customer service was outstanding. I ordered what i thought would fit my frame and turned out to be wrong. Troy was quick to help out and had a new one in route the same day. New one works like a champ. Great buy!
fit gun well sighted in eazy quality was above my expectations it made gun more fun to use I will get one for my 40cal
Perfect fit, easy adjustment, switch on and off from either side, tucks right up to trigger guard. A Lot more money than others on here but this one is just right.
it is great that someone developed a Laser Sight for the unique rail on such an 'iconic' firearm as the SW40VE
This sight installed easy and works great for me. It was reasonable priced for a low end laser solution for me. Thanx. E K
This Laser is Great !! .. Armalaser is a Great Reasonably Priced Product !!. I have one on my Taurus 9MM also .
The Stingray laser sight for my sw40ve is perfect! Ordering it was a breeze and shipping was fast. I would definetly recommend this product.
Stays lined up good but switch is stiff. I'll buy crimson trace for next gun , much smoother switches. Word....
Sits flush and very easy to calibrate the laser. Doesn't feel / seem flimsy either, which is what I feared.
Answer: yes
