Sound Loc trashed my accuracy but i got it back

I order a sound loc kit for my Talon SS and received it last night and installed it this evening. Stepped out to the shooting bench and started shooting at a 40 yard target and was I dissapointed. It shot 2 in groups and was all over the place. I had also ran a dry swab through the barrel while I had it out and figured it would settle down once I got the barrel seasoned but that was not the case. It stayed bad after a 100 plus shots.

I finally pulled the Sound lock out and it went back to decent groups. I was aggravated that I had spent that much money on a factory set up and it not work. I tinkered some more and decided to line the slots up on the top rather and staggered like the drawing in the instructions. It was an instant fix my groups went back to 1/2″ like before. Not sure if anyone else has ran into this issue but if you have try lining up the slots……..
