Smith and Wesson SW Sigma SW40VE SW9VE SW9 SW40 Rail Adapter for attaching laser red dot optic sights

My husband and I installed this adapter on his Sigma together. Took less time than changing the battery in a flashlight. The adapter feels tough and doesn’t wobble. Now he’s got a weapon light where before nothing would fit.

I swapped this adapter onto an SW40VE that I use for home defense. The fit was precise and it allowed me to use the light and laser combo I already have without buying a whole new gun. Screws tightened snugly and haven’t loosened up at all.

If you want to add accessories to your Sigma pistol this little adapter is the easiest way to do it. No fancy machining but it’s sturdy and solid. My laser and light both mounted cleanly, and nothing has moved even after repeated range trips.

I was skeptical at first because it’s a small piece, but this rail adapter made a huge difference in my Sigma build. My TLR-7A fits securely on the adapter and I haven’t had to retighten anything after shooting a couple hundred rounds. Installation was straightforward and the fit was spot on.

My Sigma came without a usable rail and most lights wouldn’t fit. This adapter changes that entirely. It’s made from solid nylon and the steel screws feel substantial compared to some cheap bits I’ve used in the past. Mounting hardware was included and the whole thing feels like it belongs there.

Works Exactly as Advertised
