Still looking at them but not as closely -
1. A SCCY was not rated to shoot +P ammo - while the older manual ~2015 stated TO NEVER fire +p - the 2017 users manual says:
WARNING
+P CARTRIDGES SHOULD ONLY BE USED ON A LIMITED BASIS
IN THE MODEL CPX.
This type of ammunition creates much higher chamber pressures than standard
ammunition. Never fire more than 50 rounds of +P ammunition per session

2. This may assist with your decision on carrying the SCCY for CCW purpose.
Take a single round of ammo and the SCCY but leave the magazine in the range bag. Try to chamber/put slide in to battery you will not be able to fire it.
A SCCY needs to feed the cartridge from a magazine and there is no way around this SCCY characteristic. The shape of the extractor will not cam over the rim of a 9mm cartridge that is chambered. The only way for a extractor to grip the shell is to strip it from a magazine. So if a SCCY fails to extract a fired shell you will have to
a) Inset something down the barrel to dislodge the shell or
b) Use a fingernail, knife etc. to pry out the shell from the chamber with the slide locked back.
I carry a KAHR CW45 right now, if it has a FTE malfunction, I can tap, rack, assess remedial action because the extractor is designed to cam over the edge of the shell.
I spoke with Jason at SCCY and he said that is exactly how the CPX extractor is designed to operate.
I am less interested in this as a CCW carry gun now than I was before.
I will most likely still purchase one but will not carry it as they intend it to be carried.
