Wow! That's a he!! of a savings. IIRC I paid about $560+- for the pistol, then after waiting for a couple months was able to buy the SMSc sight for another $199 I think (might have been $299), just don't remember for sure.
The sight wasn't even available when I bought the Hellcat, but I knew the gun was going to sell pretty fast and I didn't want to have to wait for that too, so I bought it as soon as it was available to me. So far no complaints. However, I've not had opportunity to shoot as many/much as I'd like to before I start carrying it. Only a couple hundred rnds as of now, but with zero issues.
This is not a complaint by any means on the price I paid, I got what I wanted. Just commenting what a deal you got.
