Welcome to the forum. Nice video. I am glad to see that your grip is properly utilizing HK's engineering and has your finger in the front of the trigger guard to decrease muzzle flip. I am so tired of seeing people ruined with thumbs up only use. HK has done a fine job of creating that finger weld on the front of the guards. From the USP to the VP9 and sks... The HK proper hold sure does make accuracy improve ten thousand fold.
Good luck in the competitions. make us HK owners proud!
