Ha. Ha. 
For your shotgun I suggest a red dot. Red dots are good to about 300 to 400 meters if you have decent eyesight, they're fast, and a shotgun doesn't have much range beyond 100 yards. It would be perfect for you.
I suggest a Millet Red dot. They cost about $100 and they will get the job done. I used one on my AR before I sold it.
As for Eagle Peak, I don't like going there. They have a fantastic setup, but they won't allow FMJ rifle rounds there. That sucks because hollow point 5.56 rounds are friggin expensive.
As for me...
I have a few firearms but my two favorite are my XD-9 Subcompact and my MSAR E4. The MSAR takes AR mags and I put an Israeli MARS sight on it with a visible spectrum laser.
Yeah I'm going the red dot route. Just need to find one that can handle the recoil of shooting slugs, compared to buckshot/rifle rounds, without breaking, losing zero.
I believe the FMJ rule is because they dont have a certain amount of yardage of their property per state law or insurance regulations. I dont think Reds lets you either. I mean I like Eagle Peak, because I go during the day on Mondays and there is no one there, so I can call cease fires whenever I want, take my time, and occasionally double tap (if no one is around). So I figure, just sneak in some FMJs mixed in with a HPs in a HP box.
I went with a Glock 26 1. because they werent making XD Subcompacts yet 2. I like 9mm for practice (it's cheap) 3. It's smaller than a 17 or 19 but shoots the same (For me) more or less. I wish I would have gotten a 27 and a conversion barrell so I could pratice with mostly 9mm, and carry 40 everyday
I think Z said way back when, that when he was APD he carried an S&W MP40.
Thats a neat looking shotgun, I always wonder why the double magazine tube idea was never used, probably due to some gun makers wanting their shotguns to be associated with Hunting and not Self Defense (Remington for example)
