What a year so far.. Who would have thought adding the SLS machine would accelerate prototype parts this fast. With USPSA Nationals around the corner, I hope we aren't too late. Adding 4.7 ounces to a Production or Carry Optics Glock is drastic. I honestly feel it's more noticable than when we came out with the Sig version in 2018. I can't thank you all enough. Your support of Shooting Sports Innovations keeps this small business rolling. More to come.. stay tuned.
