Upgrades for my rebel LE?

[rix]

I recently purchased a new Rebel LE and I want to start upgrading it. I already have a new barrel, and I was wondering what else I could get. Also, is there any way to fit dye stickies on the grip? It's a 45 grip, but there's only one screwhole in the middle.

the grip is nice the way it is, but if you really want to, just drill a hole in it. trust me the grip is one of the best out there. I am not sure if pmi or spyder sight rails fit on it, I will check it out, but they said it is a spyder clone, so most spyder upgrades will go on it.
