Obsidian Arms Sig Sauer P320 21 Round Magazine Base Pad Extension. Machined from aircraft grade 6061 aluminum and military grade hard coat anodized in Black. Upgrade your current factory polymer base pad with this aluminum base pad to add a little extra weight to allow your mags to drop easier and also add 1 extra round when using 9mm or .40S&W. This basepad will fit any Sig Sauer factory grip module but will only fit onto the 21 round 9mm or 18 round 40 S&W magazines. This upgraded base pad also fits in the 140mm gauge for competition shooting and includes a unique retainer plate. All together, this base pad will allow you to conduct tactical reloads and easily drop the mag without worry of it breaking when hitting the ground.
