DexterGSP--Your gun isn't dirty. This is dirty. After a bullseye match. That I won. This is from late 2016, two years after the post listed in a reply above. I'll shoot this pistol in the morning. It will run fine.
The difference is that this is .22 gunk from a Kadet kit and it builds up a lot faster than centerfire gunk. I would spend all my time cleaning the 75B frame if I was in to cleanliness. Futile with the .22.
This frame has nearly 50k rounds on it, and I clean it once a year. Now the barrel, ramp, breech face, firing pin, and firing pin channel, as well as the extractor and magazines get cleaned regularly, since it is a .22. But I've gone 2k-3k on a P-09 without cleaning it at all, just add oil.
