I am finally determined to get a P-320, but I am having difficulty in choosing between 9mm and 40 S&W, as well as between the full size and carry model. I like both calibers, but I do not have the ability to try one of these pistols prior to purchase. I suppose my question to members who own a P-320 in 40 S&W would be, if you had the opportunity to purchase another pistol, would you still choose the 40 or instead, go with a 9mm model?

Believe that you would enjoy shooting the 9MM more - easier to shoot and I believe that the round is the sweet spot for performace, price of ammo and enjoyment of shooting.

Now I am a glock guy and have the 34 and 19 - had the baby 26 - but let it go to get the 34.  I could shoot the fire out of that 26 - just enjoy the larger sizes better.

Does that help?

I prefer 9mm (used to carry 40 s&w). Cost, work/personal carry and resale tends to lean more towards 9mm.  I ended up getting a Carry, because I can easily decrease the size (pistol height) of the pistol with a simple frame swap.  The full size leaves you with only that option without doing a slide/frame swap.  I also wanted a pistol sized closer to the G19 and not the G17.

You can review the specs to see sizing variations.

I thought that you would swap the guts into any frame - you are changing the slides and frame out.

the mags will work larger to smaller, but not the other way around.

Compact and Carry use the same slide.  Frame difference: Comp (5.3 Height) vs Carry (5.5 Height)  Comp (15+1) vs Carry (17+1).  A cheap quick change in height is a frame swap.  If you want a larger change (i.e. Caliber/Sub Comp change), you'll need a kit.

I forgot to mention magazine change.

Get the carry in 9mm.  You can make the compact and subcompact with a grip change.  9 cheaper than 40 is a major consideration.  David

I ordered a P-320 Compact 9mm from Top Gun Supply this morning. Looking forward to shooting it next week.

I have both calibers in my p320. Actually two guns. I really do not feel the difference when shooting. Ammo price wise it is the nine, unless you catch a sale at your LGS.

As far as grip moduals, I have them from the carry to subcompact. The carry is fun but the compact is more practicle. Subcompact is good for concealed carry. I prefer the compact for over all use.. Full size mags are good for over all use in all sizes.

This is the route I'm going. The Carry seems perfect. Haven't been this excited to purchase a handgun in a while.

I would do 9mm carry.

I was able to get to the range yesterday and shoot the P320. It had zero issues through 200 rds, but I was consistently hitting about three inches left of point of aim, regardless of how much I stressed proper grip and finger placement.

I like the trigger and I think it has a little shorter reset than my Glocks. The one thing I found odd, was the amount of felt recoil I noticed, especially for a 9mm. Not what I expected using Federal 115 grain aluminum cased and Perfecta 115 grain brass cased ammo. I am going to drift the rear sight a bit to the right and return to range next weekend.

Overall, I am not as initially impressed with this pistol as I had hoped I would be. However, I said the same about my M&P45 when I first fired it, but it has become one of my best shooting pistols. Hopefully I will say the same about the P320 in time.

Try the APEX flat trigger for the P320. It made a significant improvement in my shooting (and I used to hit left as well).
