Which one would you choose, and why?

I prefer (and own) a G19. More round count and easiest recoil management and the better ballistics of 40s&w are not enough counterpart for me, I'm sure you will get different opinions.

Love my G19. I just prefer the 9mm. Of course you could get a 23 and buy a 9mm barrel for it and have both.

I have a g19c first pistol I purchased on my own at 21. With the compensated version in 9mm is like no recoil, funny over the years .40 S&W is my favorite caliber either is s great choice, as jermz stated you can buy a g23 and technically have 3 guns in 1. .40 sw-.357 sig-9mm

G19 is the best all around 9mm on the market. I'm not a big fan of the 40.

I have G23 that I carry off duty because I am issued a .40 (G22) at work and have ammo available.

 

If that's wasn't the case, I would have a G19.

Neither, buy HK.

Lol

I have both. Had the G23 first. It's not much fun to shoot, although I hear the gen. 4's are better.

The gen4 models of the g23 are very different recoil wise. I'd get the g23 a d get a conversion barrel

Have both. Love the 19 was pressured into the 23....everyone else has one.

I own both in Gen 4. The 23 has more recoil for sure. Follow up shots are faster with the 19. 2 more rounds with the 19. If I could only have one I would get the 19.

 

 

Lol

Or a G19 and G23 for the same price as the HK.

Like others have mentioned buy a 23 and a 9mm barrel. 2 cailbers in one. My lone wolf conversion barrel has run flawless.

I second that. I have a G22 and a KKM 9mm conversion barrel - two guns in one!

Buy an HK or even better an M&P then put an Apex kit in it.

I Agree. Many others firearms on the market that are comparable. Glocks are awesome guns but they are just so plain looking but that I think that is what most owners like about them. Also they run flawlessly on any ammo. I was set on getting a Glock as my first gun. Shot a G19 and G34 and loved them both. Ended up getting a Walther because the trigger was much better. I am sure I will add a Glock to my collection one day but probably get a G35 for the range.

This is what I would do.

I agree. For me ballistics is an intellectual exercise much like which shotgun kills better, a 12 or 20 gauge. Shot placement and penetration are all that count. Energy and small fractions of an inch in size rarely matter. Since 2003 modern bullet design has negated most of the differences among the popular defensive rounds starting at 9mm. Just take a look at this chart and see how a 9mm does when stacked against a 40 and 45. I know that I can put more rounds more accurately into a target in a given time period with a 9mm than a larger caliber.

 

Notice how non of these bullets shown are +P and that they all pass the FBI penetration test in gel. If you have ever watched a surgery you will know that your insides can be stretched and moved more than you can imagine without suffering any injury. We are basically talking about the difference between being hit by a 20 lb. sledgehammer versus a 25 lb. one. Sure the numbers favor the great weight but in real life they both will do the job.

 

Very informative. Thanks Old Dog.

I've got a Gen 4 Glock 23, so I guess that tells you what I'd vote. I wanted a .40, I already own two 9mm Sigs. To be honest, the Glocks in 9mm don't interest me all that much. I want a Glock 20 and a 21, so I'll eventually get those as well, but the only 9mm Glock I really want would be the G18

 

If you haven't got any 9mm, then maybe the 19 is a good gun, the extra capacity is a plus....but I believe you can use a G22 mag in the G23 so there's 15 right there. As others mentioned, you can always do different barrels, and get a .40, .357sig, 9mm, and I'm assuming .22LR.

 

I'm happy with my Gen4 G23...but all this said...I'll own a lot more Sigs than Glocks when I'm "done" buying guns...

 

 

"Done" ...HAH!

If you believe Larry Vickers, he said on Tac TV that the best Glocks are the 9mm versions. It's what they were designed for and between the 17 and 19, most people will fit and get the job done.

I had a 23... and I carry a 27...  So I really had no use for the 23.. sold it and got the 22.. I prefer the full size out of all of them.....

 

 

as to get the 40 or 9... the answer is obvious.. get the 40.. so you have the option for 40 OR 9...

why would you ever limit yourself to just 9 when you could have both?

Glock 19_Gen4 = best all around 9mm

 

but I carry a G27_Gen4.  -go figure!

Can you put a 23 slide on a 19 and vice versa?  Does the ejector have to be swapped?  Anyone know?

23 & 19 have the same frame size.

They use different ejectors. Very easy to change ejectors.

I had a G23 and ditched it for my G19. Glocks = 9mm for sure! There's absolutely no benefit with .40 today.

Also, Glock .40s have a history of being unreliable when attaching a weapon mounted light. If a WML is something you may want to use one day, keep this in mind.
