I recently did a little experimenting with my franchi raptor to see what difference a higher comb would make. I have a relatively long neck and high cheek bones, I've known this for a long time but still bought a gun that didn't fit me - I've no idea what I was thinking to be honest!
I built the comb up a fair way with tape and high density foam until my pupil was just above the bead when viewed in a mirror, it feels much better and I'm shooting quite a bit better with it too. I patterned the gun and every choke shot a foot or so low at 40yds except the full choke which was still low but more like 4-6". I've left that choke in and, despite the tighter pattern, I'm shooting even better now!
So, I emailed a guy about having an adjustable comb fitted and the price seems quite reasonable £190 but he did say it may not be possible because auto's often don't have much wood to work with.
I've no other issues with the gun, it's reliable and I've yet to find any ammunition it doesn't cycle well. It's also a nice looking gun but I must admit I'd happily sell if I found an auto that fits me properly.
What would you do? Can you think of a similar gun (possibly beretta or similar) that has a high comb or can be adjusted to suit me (the raptor has shims but none even come close, the comb would need to be on the high side in the first place).
