For defensive builds, I prefer the steel Remington extensions over the aluminum Nordic parts for their simplicity and durability. For just the +2 or +3 kits that fit under combat barrels, I doubt the steel adds a noticeable amount of weight. I also have a bayonet for my shotgun (mostly just for fun, but I'll be bringing it along if I ever go pig hunting), and the Remington extensions are designed to mount one, while most aftermarket kits aren't.
If you're sticking with the Remington extension, I'd avoid the Nordic follower. Remington extensions have a follower stop built in, and the extra length of the Nordic follower will reduce your magazine capacity slightly if the two are used together. I have an S&J follower in mine, and am extremely pleased with it. If you want metal though, there are some other good aluminum and stainless steel options out there that are a normal length.

I'm the same way, but with a different caliber. I have a Gen4 Glock 31 (.357 SIG), and I'd like to add a 33 to match it. I wouldn't mind picking up some 9x19 magazines and barrels at some point though, which would effectively convert them to a 17 and 26 when desired.
