So let's compare and contrast what I consider to be the two best guns on the market today: the Glock 19 and the Sig Sauer P320C. I must admit that if I were not so vested in the Glock, or had the P320C been available when I designated the G19 as my GTG (go to gun), I very likely would be carrying the P320C today. I'm still not sure I won't at some point convert, although the HK VP9 and VP9sk certainly call to me, but since I am on a budget I have to be smart about it all, smart being somewhat subjective here.
I thought I would talk about the things I like and dislike about both, with hopes of some of you chiming in to do the same. So let's start with the G19. As I've said so many times before, what makes this gun so special is its unique size. In a world of full size and subs, the G19 fuses these two worlds in a way no other gun ever has. It is large enough to be used as a duty gun, with a full 4" barrel and grip that allows almost every shooter to get a full purchase, yet it is small enough to conceal very easily. It is thin and sleek with minimal levers that are extremely low profile making it virtually snag free and easy to carry IWB or OWB. When one considers that, along with cost, reliability, capacity/firepower, ease of use/maintenance, aftermarket support, etc., it is easy to see why the Glock 19 is the most popular handgun in the world.
What I don't like about it. Not much! If I had to pick something to complain about it would have to be the trigger guard. It's small, making it harder for some to get their fingers to the trigger with gloves on, and it needs more relief under it as to not give people the infamous "Glock knuckle". I would also prefer it to have a standard 1913 picatinny rail rather than the proprietary Glock rail, and there would be nothing wrong with removing the finger grooves, equipping it with ambi controls, and perhaps beveling the muzzle like it is done on the G26. Although I like the trigger, it could be made a little smoother out of the box.
Now to the P320C. Well, what's not to like? It is essentially the same size of the G19, which makes it equally as formidable, and I think it will make a nice challenger to the vaunted 19. It has a very nice trigger. Although I know some have said they don't like the "double click," that really doesn't bother me. All guns have their little intricacies that are unique to their design, and there is nothing wrong with that.
The whole "modularity" really isn't my thing, but it is definitely something that is extremely beneficial to the individual user. There are a number of advantages this design gives the user, most notably is probably the ability to easily and quickly replace a broken grip frame. One can have an extra or two in their personal inventory to be able to replace a broken frame in a snap, and I think that is very cool. I also love the fact that these guns have a 1913 rail, a beveled muzzle, a bigger and cut trigger guard, and ambi controls, and it is a bit lighter than the G19.
What I don't like? Well...again, not much. If I had to pick something apart I would have a hard time doing so, but hear goes. Just for the sake of finding something, I would say the barrel is a little shorter than the 4" barrel in the G19, and the grip is slightly longer making it a little harder to conceal, but not really. If I were going to argue a disadvantage compared to the Glock, I'd have to mention that. Also, the bore axis is significantly higher. The gun is slightly wider than the G19, but honestly, not enough to make a relevant difference. It's really silly to even mention it, but I'm looking for "anything" that could be a gripe. This gun seems to have everything a G19 wants to have, other than the illustrious reputation of sheer dependability. The only thing that can change that is time, which the P320 will have plenty of now that it was chosen for the US military sidearm.
Conclusion: If you're looking for a perfect EDC/GTG that will do pretty much everything you need a gun to do, you simply cannot go wrong with either of these guns, but if you're not already in a Glock, like me, you may want to give the P320C a serious look.
