I've had the same problem with Aguila "Super Extra" 40 gr CPRN 1255fps spent brass sticking in my S&W 43C. I've had to bang on the ejection rod to get the brass out sometimes, they were stuck so tight.

Seems like high velocity brands that are closer to 1200fps work better.
Standard velocity even better.

But Aguila is the worst offender for spent brass sticking in my 43C.
