Pistol Picatinny Rail Adapter Base
For Smith & Wesson S&W Sigma
With this adapter, you can put any Weaver or Picatinny accessory on your Smith and Wesson sigma or sw9ve sw40ve pistol. S&W puts a proprietary rail system on the sigma normally, and no one really makes a good accessory for direct fitment. Save yourself the time and hassle, buy this adaptor and you will be able to equip any standard accessory laser flashlight, or whatever you want, using this adapter.
Rail length: (1.8 inch)
