2023年8月3日 · I bought a P320 Custom Works FCU in black from Duke's Sport Shop, Inc. a couple months ago for $299.99 with free shipping to my local FFL. The nice thing is SIG will email you a code for 10% off accessories at their online store when you register the FCU with them so it's not a bad deal overall.

2021年6月14日 · I purchased the FCU in MA two months ago with the $50 mock up over $299.99 MSRP and than tax. I don't think it's worth it to buy the FCU unless you like the TI color and go all non-sig off the shelf custom parts. Pretty sure I spent more …

2021年4月6日 · In my opinion, the .45 FCU is the universal FCU. As long as you use matching components, i.e., 9mm barrel with 9mm slide, 9/40/357 RSA, 9mm magazine, and 9/40/357 module, or .45 barrel with .45 slide, .45 RSA, .45 magazine, and .45 module, the .45 FCU will work as advertised, with the exception of the takedown lever as described above.

2022年6月5日 · Only anecdotal, but I have two P320 CW FCU's, and one P365 CW FCU, and the CW FCU's all measure lower pulls than their standard counterparts. Out of the box I didn't notice much difference, but after 100 rounds on each, the CW has a noticeably smoother and lighter trigger pull. Not by much. I'm measuring ~3.6 on the CW vs. ~3.9 on my standard ...

2020年7月8日 · I'll have to find that fcu and wait to afford it and then buy the right one. I'll have this perfectly good fcu on hand if I feel groggy and want two p320s I guess. But the good part is it broke my cost of the jig into two pistols. So that's a plus. 75 per fcu instead of $150 on one. But c'mon ab prototype, jsd, apex or bison or buffalo something.

2022年9月12日 · I was told by a SIG customer service rep that there is no functional difference between the Custom Works FCU and the regular P320 FCU. He said the Custom Works FCU does not contain any "upgraded" parts and that all of the parts available on SIG's Small Parts Shopper are completely interchangeable between the two FCUs.

2024年12月12日 · If indeed the FCU’s on certain guns are rubbing the springs to failure then no amount of new springs is going to fix that. It looks like the best way forward is to observe the FCU looking for any rub marks and contact Sig if they present or clearance the areas yourself. It sounds like a relatively rare condition or it would be on blast ...

2021年10月30日 · The only option available today is to have your FCU Frame cut for a Manual Safety. My thought is: Why don't ALL P320 FCU Frames have the Manual Safety Cut. Just a simple cut..FCU frames function perfectly either WITH it as a Manual Safety FCU Frame or NOT. Just 1 Pin for a Non MS FCU or the MS Parts to function as a Manual Safety FCU..So Simple.
