I bought a Sig P320 Compact in .45 ACP, and it is my favorite gun! That’s saying a lot when I also own guns by HK, Berretta, Smith&Wesson, and Walther. Very little recoil for a .45. Great ergonomics as well!

Good firearm, but not without issues
Bought a p320c new in early October. This is my first striker fired handgun. I chose a Sig based on reputation. On my second trip to the range, after about 75 rounds, I started having failure to eject, round after round. I couldn’t figure out why. Asked the range gunsmith if he could take a look. He said the extractor was missing. Apparently it blew out of the slide? Never heard of such a thing. After contacting Sig and waiting several weeks, they sent me a new extractor, except they sent me the wrong model. Now I have to still wait for the correct part. It is going on three weeks now. I hope once I get the new extractor in ther wo t be any more issues. This now makes the second Sig I own that has had a catastrophic failure.

Love my Sigs
This was my first hand gun purchase back in 2022. Absolutely love this gun. I’ve used it as my carry and now my home defense weapon. I have 800 rounds thru it without any malfunctions. Over the years, since I have purchased a P220, P226, P229 Legion, P320 M17 and M18 and P365XL for concealed carry. Love them all.

Phenomenal pistol.
This pistol has been reliable and accurate every time. Now, that sounds like a Toyota Corolla, so lets give it more depth. The grip, the first time I handled it, was simply perfect, no other grip felt like it as if made for my hands. Using it at the range has been amazing, hundreds of rounds with no issues, but it is a very smooth operation pistol. Cleaning it is straight forward, easy to disassemble and put it back together. Buying a different grip, the Carry grip, gives me two different guns and the changeover is very simple.

Solid performer
For the money, it’s great. Has become my favorite range gun. It did need several hundred rounds of 124 grain ammo before it shot consistently. Solid performance now.

P320
First firearm I have owned and I can honestly say I made a great choice. I have used other firearms in the past, and none can compare to the P320.

I own quite a few handguns of different makes but I’ve never owned a Sig Sauer because of their price. I recently purchased this P320 compact in 9mm. Sigs first striker-fired moderately-priced semi-auto pistol. I just put a box of shells through this pistol and I was totally impressed with it. Especially the trigger pull. It’s stock sights are right on. It is very accurate it seems to be well made and for a medium price gun and it has a great trigger on it. I can’t say that much for other makes of pistols I’ve got in that price range. If anybody’s looking for a good full size or compact pistol I would recommend this pistol. The compact version seems to be somewhere between a compact and a subcompact and would probably work well for concealed carry. Very happy with this purchase

Great dependable pistol
I like that there is an option for a manual safety on your 320. I also picked the P320 for the grip size and the weight of the firearm.
