How Do I Decide Which New Gun to Buy? (Glock 17 or Sig P320)

Tyler in NC sends in today’s Q&A podcast asking about how to decide between two guns.

Tyler is looking for a new blaster to use as a competition pistol and some nightstand duty, etc. He’s shot Glock 17’s in the past and they shoot well for him, but he also likes the Sig P320, but he can’t decide which one to buy.

I think if you weigh out all of the pro’s and con’s between these two pistols, you’ll probably find that the Sig P320 will end up costing a bit more, since you’ll probably end up buying 3-4 magazines for either gun, and the Sig P320 magazines cost about twice as much as Glock magazines do.


I think that extra (maybe?) $200 in Sig parts isn’t all that important in the long term. If you like the Sig P320 more than the Glock, then that’s the gun you should get. I think “I like it” is pretty important when it comes to having a gun that you’re going to shoot competitively.

I had a similar situation when I ditched my S&W M&P Pro 9mm for a Glock 34. I can’t really quantify to you that the Glock 34 is better than the M&P, but I like it better, so I made the switch, and I’ve improved as a shooter since doing do.

I think based on Tyler’s voicemail that he likes the Sig P320 more than the Glock.

If you’d like to send in a question for the Q&A podcast, I’d like to find an answer for it. Here’s how to send it in.

  1. Excellent response, Mr. Apps, as usual. If I may be so bold as to chime in with a couple of additional notes on the topic…

    Your suggestion that Tyler strongly consider choosing the pistol he likes more is actually backed up by solid academic research. With a couple of graduate degrees in adult education, and without boring you with chapter and verse, I can tell you the reality is that adults will more often perform activities they enjoy and will learn more from those activities. In this case, if a shooter likes a given gun more (and assuming that, as in this particular case, there are no significant differences in the quality and utility of the pistols), the shooter will be far more likely to handle the weapon more, to practice with it more, to compete with it more and, therefore, to learn more in that process. The entire experience will be more enjoyable, more frequently pursued and better training will ensue as a result. So, good advice on your part!

    I would also note that Tyler says he already has a compact version of the SIG he is considering buying. Having a larger version of the same pistol he already has (and enjoys) will potentially streamline not only his logistics (holsters, mag pouches, etc) but it will also reduce any resultant learning curve associated with a differing manual of arms. As the guns are virtual copies of one another, though on slightly different scales, any practice on one will directly apply to the other. A small thing, no doubt, but a thing to consider nonetheless.

    My two cents. I hope it adds to the conversation.
