I got my new Compact Small grip module today and put it on with some great difficulty installing the take down lever. Finally got it put together and put 200 rounds through her. Took it home to clean and had to physically force the take down lever to remove the slide. Tried everything I know to rotate the lever to remove the FCU but couldn't remove the lever from the gun. I had no problem when I had the medium module on it but the small won't budge when trying to move it. Any thoughts of is it back to Sig?
