In what can only be described as quite the coincidence, the SIG P320 purchased by TTAG to drop test arrived back, all voluntarily upgraded, right as news of the Honor Guard’s safety failings was hitting the TTAG Drop Safety Desk. As you’d expect, we hit the range to make sure SIG’s changes did, in fact, result in a “drop safe” pistol and to see if this affected trigger pull quality . . .
As with the Honor Guard, I used a large rubber mallet to smack the rear of the P320’s slide. Despite wailing on it extremely hard, the gun did not discharge. In fact, the striker never slipped at all and the trigger remained active with a standard pull weight, distance, and break after any amount of hammering.
This was not the case prior to the voluntary upgrade, and is a far cry from what we found on the Honor Guard, which was dropping its striker and discharging with a fraction of the impact force.
No, sorry, we didn’t drop this pistol onto concrete again. Two reasons: SIG satisfied us with their own demonstrations of the upgraded gun’s drop safety, and the mallet test had been fully sufficient to cause pre-upgrade P320s to fire. No need to go mucking up the rear sight, slide, and frame (and RF’s garage floor) again.
I still wouldn’t call this the drop-safiest gun on the planet or anything, but I now trust it to handle any reasonable drop, impact, or vibration that a gun may see in regular EDC or duty use.
SIG has replaced the trigger shoe with a lower-mass version. Hollowed out on the back, it’s light weight and low drag. It increases drop safety by reducing the trigger’s inertia. It even looks better, too.
As for feel, it’s effectively the same. Same pull weight — this one’s right at 6 lbs, which is actually lighter than many pre-upgrade guns measured — same pull length, same clean break, same short-ish reset.
Some users will notice that the little “click” feel part way through the pre-upgrade gun’s trigger pull is now gone. If that was a gripe for you, as it was for some, then this voluntary safety upgrade can also be considered a trigger pull quality upgrade.
If you own a P320, go to SIG’s upgrade page here and get your gun upgraded. There’s zero cost to you and, as far as we can tell, zero reasons not to do it. The upgraded trigger looks better, feels slightly better, and is, of course, safer. Wins all around.
