SCCY has a great warranty, but I had two warranty issues within the first 100 rounds to get mine working right. If you look at the SCCY forums things along this line seem to not be uncommon. Now that its working properly, and I have a bunch more rounds through it I'll say that overall I like the gun. The trigger pull is smooth but long and heavy at 9 lbs, however I will say that I am used to single actions with pretty light, short trigger pulls, so it you are more used to a DAO it may not bother you.
The CPX3 has been promised for a number of years however the release date keeps moving. Personally, as the CPX3 in .380 ACP is almost the same size and weight as the CPX2 in 9mm I don't really see the rationale.
I will say though that their customer service is helpful, quick and friendly.
