FNS40_DBMOD Function changes to frame: -tightened the sear assembly pocket -Looser tolerance for Magwell -changed mag release in the horizontal axis to fit mag release -added larger shelf for trigger safety -thickened front locking block pin area -thickened rear sear assembly/rail pin area - it is suggested you find a longer roll pin for this area to take advantage of the increase in material. Cosmetic Changes: -Extensive shaping to grip -P80 style trigger guard -thickened the sides of the frame and added stippling sections -added ribs to grip for added pleasure -idk it’s totally different but also the same. I know the instructions say print Magwell down, I don't do that...seems to be great tho. Just clean out your supports ya noob. I recognize the original developers put so much work into this frame. Thanks to TM18271998 and nguyenkvvn This isn’t the greatest frame in the world. This is just a tribute. Oh...there's a magazine baseplate too. It matches the frame sort of. Thanks, Danishbulldog DBFirearms (keep an eye out for db9 dropping soon)
