Well first of all, congratulations on making what I think is a great decision !
I would add the ambi-safety and the countersunk slide stop.....and depending on which sights you bought, I might consider some of their newer options with the battle sight and a fibre optic front sight...

This CQB in 5" in .45 acp is my primary carry gun / and I wish I'd specd it with an ambi-safety. If I ever need to send it back to the factory for re-work, I'll have them add it - and the countersunk slide stop and probably the speed chute - but mine only has about 25,000 rds thru it ..and nothing wrong with it. ( I have an ambi safety on my Wilson Protector model 5" - and the speed chute - and I like both options ).
