It's a pin of them all

by Ian McConnell, Verified Owner from MD, United States Written on January 15, 2025
Definitely a pin of them all, and luckily one that works. I damaged or misplaced the retaining spring for the FCU spring on my P365 at some point. This new pin came with two springs in case I do it again.

Essential Replacement Set for SIG P365 – Works Perfectly!

by Hilluminati, Verified Owner from TX, United States Written on December 18, 2024
The SIG SAUER P365 Receiver Pin and springs set works perfectly. I originally bought the set for the springs since they’re so easy to lose—and, sure enough, I lost mine. Once the set arrived, I replaced the original pin and installed the new spring, and everything worked like a charm. It’s a straightforward process, hard to mess up, but the quality is great. I definitely recommend purchasing this set, even if just for the two extra springs—they’re worth it!

Buy Several. I know I'll lose them.

One of the greatest advantages of Sig's new striker fired pistols is the removable (FCU fire control unit) that allows these pistols to be completely customized,or at least individualized,firearms around. Three really nice features to customize are a optical sight, the grip, and the trigger. Probably the most impactful are the grip frames. I've seen aftermarket grips available from like $40 to over $400. Even just Sig OEM grips have a good range of significantly different options. Besides OEM there are many aftermarket grips available as well. They can differ greatly enough that the 'pistol'can feel different and making the firear fit you w/o having to sell a gun (or just adding it to the Oh, well pile in the safe) and tey to find something that fits better. This can also change the version of the gun series you purchased. Ie., buying an XL grip or a macro grip to an original p365 can make it hold extra rounds (w/ an extension grip base) or a differently sized magazine, etc. can make the pistol much more versitile. The red dot is kinda self explanitory. There are also a good number of triggers available that can give a different feel (curved to flat) or reduce take-up, weight, over travel, crispness, reset distance and strength of how fast/easy the trigger pushes back to It's reset. To do either the grip or the trigger the FCU needs to me removed from the frame. This pin in this listing is the way the fcu attaches to grips and can easily be earen by the recliner or lost.
Pros:
  • Available and good to have an extra
Cons:
  • None
Would recommend: Yes
