I've got one on my P10C. It took a little fitting and modding to get it 100% for me. The little feet on the lower front were pretty sharp and the inside edges where the trigger sagety flexes was too. I took it back out and dremeled it with a felt bob and smootheed it out. That took care of that small problem. then I took a smooth file and opened up the trigger slot in the frame just a hair. At times it would flex just enough to keep the trigger from fulling pulling enough to release the striker without an extra hard pull. Since then, it has been absolutley perfect. It's much better feeling on my finger pad than the stock plastic trigger and it seems to enhance and smooth out the overall pull. I didn't use the lighter striker springs as mine was light enough already. Made a really good trigger into a really great trigger.
