Different sights are not a problem for me, tons of ambient light in my house, plus I have great night vision, I like carrots. If you really want to get creative, they do sell good glow in the dark paint that you could use over the existing paint on the sights.
1. A flux capacitor would be great, then I can shoot the motherf-er before he even knows I'm going to. :shock:
2. Accessory rail would be nice. I would love to be able to mount and unmount a laser/tac-light without extensive effort.
3. It would be great if there were no difference between the C9 and C9 Comp. They should be the same gun, IMO.
4. Higher capacity mag would be nice, I can do a 10+1 on my C9 but it would be nice to take out that 12th, 13th, 14th, and 15th motherf-er before I have to reload. Plus I wouldn't have to have so many laying around. :roll:
5. Interchangeable grips, mag release button, safety, trigger, so I can pimp my C9. 8)
6. Reduce break-in time with a factory polished feed ramp. All HP has to do is not paint the feed ramp, pretty much.
Mostly the things I would change are cosmetic. I love the size and the weight, I'm a big guy with big hands. I have no problems ccw-ing my C9.
