If you're into modding, I'd suggest looking up how to do Nerf masterkey attachments on Google. Like this: http://nerfhaven.com/forums/index.php?showtopic=23896

For a backup type sidearm, if I had to stick to your list, It'd be the Maverick. Otherwise, I'd suggest the Nerf Triad. I did a small review of it on my site: Nerf Triad

Another option, if you're a fan of the Mega Nerf series of blasters, is to wait for the Mega BigShock. It's basically a Mega version of the Nerf Jolt. Looks pretty cool, IMO. I did a write up of it and a few of the other upcoming Nerf blasters here.

I think any of these would be good back up weapons. If you're running with an EAT and a Strongarm already, you need a really small and compact pocket pistol. The Triad EX-3, the Jolt, or the upcoming Mega BigShock fit this category nicely.
