FBI declares Sig 320/ ‘M17/ M18 unfit for duty

Yep that's total B.S. Testing
Put in different parts from the factory then claim it fails.


Sorry but you need to test as it ships before making any sweeping statements.

I think the main conclusion of the report is that, through pressing down/pulling up on the frame/slide, it was possible to disable the striker safety lock. They confirm this not just on the subject pistol, but on a brand new one as well.

That means that on a duty-carried gun, which is likely banging around on a daily basis in the holster, that one of the safeties can be disabled. Now what causes the striker to be released from the sear and over-riding the secondary sear notch I'm not clear on. The safety lock is the third safety. But they demonstrated that it doesn't always work.

I haven't followed this saga super closely, but I've read a little. Here is my uneducated prognostication of whats happening.

I think the safety lock is getting disengaged by jostling as the report has shown. I think the sears are releasing because of poor machining, combined with guys drawing their pistols and taking the trigger to the wall (as training says you should), but not firing. Possibly, this is reducing sear engagment on poorly-machined sears, which later causes a sear to randomly release. What I don't get is why the secondary sear notch doesn't catch the striker in those situations.

Most likely because they did not bother analyzing the dynamic behavior of the the fire control parts. The report identified sear bounce through high speed photography. That should have been fixed long before releasing the product to market. But it was not and most likely they also did not check whether deformed first engagement surfaces can kick the sear away from the striker to the point that the second notch has nothing to grab. Or, after slipping off the first notch, the sear contacts the striker, bounces off and again the second notch misses the striker.

There are many items in the fire control group that scream "amateur" (the way they tried and failed to capture the striker safety spring) or "cheapskate" (3rd world MIM garbage) or a mix of both. On top of this, you have multiple undocumented parts revisions, parts without numbers to assess their compatibility, etc.

SIG, once synonymous with sound engineering and uncompromising quality, now looks more like the Boeing of the firearms industry.

If you love CZ pistols, then send them to Cajun Gun Works for their $500 package and you'll probably be addicted to them for life.

That being said, I really like my Walther PDP series pistols a lot.

Yes I also have the HK VP9 and P30 and HK45 and USP Elite and USP Tactical and all that stuff as well.
The VP9 has a nice trigger, the others well...

Heh I got the extended firing pin and reduce power spring kit (from CGW of course!) and worked it myself. Thing is/was a dream. Had a better trigger in SA mode than my STI race gun. I seriously considered a S2 Compact or CZ-75 compact as a carry option.

…3rd world MIM garbage…

The irony in this statement is that MIM parts are from the “third world” because America has no economically viable means of offering anything.

Send a S2 Compact to CGW for their full package and well you might not go back to anything else.

This. HO LEE FUK has my S2 spoiled me.

I know everyone has their favs but CZ polymer is pretty damn good too. I shot/carried an M&P for a long while. Walther has a fantastic one (best stock striker trigger there is IMHO). The fact that everyone but Sigs works AND sig got the contract just seems sus. But then our government would NEVER be involved in backroom deals for their own benefits...

And speaking of best carry pistols, it is my obligation to say:

TWO WORLD WARS!!!!

1911 BITCHES!! I'll see myself out....

Like the ACU camo debacle? Good grief did I loath that uniform and wish for my BDU’s and DCU’s back…
