In case anyone is still curious about this topic. I just got the slide back from Patriot Defense after less than 3 wks from the time of sending the slide to them (one of the weeks being the crazy ice-pocalypse Texas endured, where someone was shutdown). I am a noob to this, but looks to be quality craftsmanship. The RDS is mounted very securely on the slide. I am excited to go sight in and shoot it. Cheers.
