I'm putting in for my stamp to SBS my shockwave. I run a side saddle the inconveniently covers the serial number. Now, I've never had anything checked or known anyone who's had anything checked, but am I asking for a problem by not being able to see the serial number? I can get the saddle off, but not without more tools than I carry. I "might" can modify it to show the number but I'm not sure.
