I have a PT145 with no issues. I ran 25 rounds the first day and put 100 down her yesterday. I have a 24/7 OSS (9mm) on order from Buds now. I had a 24/7 9mm in the past that I put over 1k rounds down her in one weekend without cleaning and well over 5k through it over the time I had it and I never had the slightest issue. The one time it failed to go bang was on a round without a primer...
