I have a USP 9mm that's only firing about every other round.... looks like a spring-related light strike since the gun is nearly spotless. It's a KG date code (11 years old if I found correct info) so I'm thinking that the springs are probably just a bit compressed/weak.
I've decided to replace all the springs on this thing rather than just one at a time, and I found everything I need at Numrich. However, they are listing some of these springs as "new style" and "old style." Can anybody tell me which a KG date code is and what the cutoff year was?
