SIG P-320 Compact In 45 ACP

Anyone that knows me certainly knows how much I like the 45acp round. When I heard the new model of the SIG 320 was coming out in 45acp in full size,carry and compact I found these as soon as I got to the range.

As most people know by now the P-320 is a modular pistol with a chassis that can be changed from one frame and slide combination to another. Now you’ll be able to get them in tan as well as the standard black. I was especially keen on trying out the compact and wondering just how much recoil there would be. As it turns out recoil isn’t a factor.


In speaking with the SIG representative we talked about recoil prior to my actually shooting it. He related that SIG tried many different spring strengths and types to reduce the recoil as much as possible. Of course I mentioned in my original review of the 320 how ergonomic the grip was. Between the correct spring being chosen and the grip the recoil wasn’t bad at all.

Again all my shots were fired from 15 yards. I fired the first mag slow fire and the second as fast as possible. The recoil was more of a push than anything you would expect from a small frame pistol in 45 acp. I was really surprised at how manageable this little pistol is. There were no misses even when I emptied the mag as fast as I could go and get back on target. The recoil wasn’t any worse than an all steel frame 1911 commander. It’s also an accurate pistol and turned in a nice tight group in slow fire. During the time I shot the pistol and watched others there were no malfunctions. The ammo used was the SIG V Crown hollowpoint defense ammo.

I would imagine anyone in the market for a compact carry pistol in this serious caliber should have a look at this SIG.

    Really want to try one out… Anyone in UT area would like to buy one and let me try it out ?

    Quite intruiging… Only thing I don’t like is the 10+1 capacity for the largest mags. Of course, that’s HK as well… :/

    Probably the one important place that Springfield and Glock have them beat. If this was 10+1 and 13+1 it would be a different story.

      You can add the PX4 Storm and CZ97 to that mix as well. Some manufacturers really just want that slimmer grip. While some say ‘f*ck it, let’s whale this sh*t up!–like the FNX45. Another way to articulate that is: “Options.”, I guess

      • Dracon1201

        I suppose… It’s just frustrating because the XD45 was comfortable when I was 14 with smaller hands, and it just makes me frustrated that other manufacturers don’t really care to alter the mags, magwells, and grips that much as to provide the extra capacity. They can and still make it viable, just more don’t. If there is an aftermarket +3, I would definitely be happy, but the length will be silly at that point for the Sig mag.

        But you are right, “options”.

      Except this is a SIG P320 compact, which is more akin to a Glock 30 than a Glock 21… right? So 10 rounds is actually par for the course.

      • Dracon1201

        The 10 rd mag is for the fullsize. Compact is 9, Subcompact is 6. It’s below the par, and the largest magazine will be 10. I can run 13-27 rd mags on backup for the Glock. So no, not quite par.

        • Adam Skrzypczak

          I just checked, and I stand corrected. Yeah, it’s 10+1, weird.

  • USMC03Vet

    I can’t find these at ranges to rent let alone buy. They are apparently selling like hotcakes.

    Also where is your target picture? Not that I don’t believe you….

    Price? I know… if you have to ask…
