The trigger pull is a little harder than the Glock, coming in at about 6.5 pounds in a weapon that has been extensively used, and the trigger is also different in some other ways from the Glock.
For a start, it is not bifurcated or tabbed as standard. Instead, the firing block pin is deactivated when the trigger is pulled.That said, a tabbed trigger is available if you are used to using this system.
Lastly, one nice feature of the trigger mechanism on the Sig is that you don’t have to remove it to field-strip the gun, which I know is a feature that some people find annoying about other striker pistols.
If you’re thinking these guns sound pretty similar, you would be correct. The differences in size and weight between these guns is so small as to be almost unnoticeable to anyone but an expert user. Instead of obsessing about these factors, therefore, I’d recommend you look to the other factors I’ve mentioned.
SO WHICH SHOULD YOU GET?
Hmmm, now we come to deciding between the two weapons. Like I said, just basing your choice on the minor differences in size and weight between the two guns is not very sensible. Similarly, the other features of these two guns, being so similar to each other, make the choice super difficult.
Both have great striker triggers, and both are small enough to conceal whilst also being big enough to see use as proper, full-sized weapon. Both have a great ammunition capacity for their size, and both can be customized with whatever sights and other items you want.
Shooting the guns reveals some differences between them, but again nothing major. The Glock 19, as you already know, shoots great. The Sig is highly regarded for its accuracy, with many reporting that it shoots very straight right out of the box.
However, on the other hand, we noticed that the Sig had a tendency to do the same thing it’s predecessors did – kick the muzzle up quite hard on each shot.Whether this affects your accuracy will ultimately depend on how the gun feels in your hand. The ergonomics of the Sig are great, as is the trigger.
I know that some people find the aggressive rake of the grip on the Glock 19 a bit hard to get used to, and this might mean that you are actually less accurate with the 19 than with the P320. It really comes down to what you are used to.
Like I said above already, while the modularity of the Sig is nice for the military, I don’t think that many civilian users will actually make use of it. So I’ll discount that in my choice.
I would say, therefore, that your choice between these two guns should really come down to one thing – caliber. The fact is that the Glock 19 only comes in 9mm. While this will not be a huge problem for 9mm enthusiasts, those of us who like to carry some .45 sometimes will be attracted to the range of chambers you get on the P320.
The Sig can be ordered in 9mm, .40 Smith and Wesson, .357 Sig, and .45 ACP. And of course, the modular design means that you can swap between calibers using Sig’s Caliber X-Change Kit, which comes bundled with the P320.
So if you want more power than the 9mm Glock can offer, go for the Sig. If you still want to go for the Glock 19, you might be looking for a Glock holster.
