I’ve been running the P10F OR in carry optics for a little over a month (4 matches so far). Previously ran a Glock 17 MOS and a CZ P09 with milled slide. The P10F OR, by far, is my favorite. I use CZC extended base pads with factory magazine springs and follower with no issue. Can load 21 rounds. I did install a HBI Theta trigger with their 3.0# striker spring. So far I have over 2,000 rounds through the gun with absolutely no issues.
