I noticed that Sig Sauer redesigned the P365 striker again to mitigate perceived primer swipe issues. The redesigned striker first appeared in the P365 XL, but is now found in all current production P365s. If your P365 exhibits primer swipe and if it concerns you, this "upgrade" may be for you. It only takes about 5 minutes to swap striker assemblies. Here is the part number of the assembly as taken from the bag it arrives in. Next, an image of the revised striker tip (before removing the assembly from the parts bag). The tip now has a more chiseled appearance as can be seen above. Here is the result after installing the new striker. Striker marks from left to right: Gen 4 Glock G26 (has a rectangular shaped striker behind the tip which leaves a faint rectangular imprint); "3rd Gen" P365 conical tipped striker with typical primer swipe; current production P365 striker with no primer swipe. The position of the slanted striker tip is indexed so that its point is at the bottom when installed in the striker channel inside the slide. (The dark spots on the primers are shadows.) I wasn't overly concerned with the primer swipe the P365 exhibited, but when I learned of the current "4th Gen" design I decided to try it. An added bonus is that it greatly improved the trigger pull by removing any hints of a gritty pull before the break. On the new striker, the area where the sear engages the striker looked like "in the white" metal. That part of the striker was lightly polished prior to installation. To me, the result was worth the $35 cost of the striker. The trigger pull is very smooth now and feels as good or better than Glocks with a 25¢ trigger job.
