The 49.

 

The 51

 

1st is 19x
The 47 or 45 are equal imo

 

I prefer the G45 over the 47 and 17 for the same reasons.

There is no need for the added sight radius and longer slide when using optics.

The velocity difference is negligible and doesn't make a difference at combat ranges.

The shorter 19 slide allows the use of a shorter holster, which in an LE patrol car environment, is easier on the ribcage.

Which is best is subjective based on you and the pistols intended uses. For me the G45 works best

Truth is the G47 is nothing more than a G17 with a shortened dust cover and guide rod assembly. IMO it shoots exactly like a Gen5 G17.

I happen to be carrying my Gen 3 G17 today, just because, and it has hit me in the ribs multiple times today just sitting in my chair in my office. It reminded me of why I don't carry it any more.

I saw actual chronograph measurements of velocity between a G17 and G45 with same ammo and the G45 was always 20 to 50 fps higher velocity than the G17 - go figure ?

Of those two the G45 balances better, the G47 is basically a G17 upper on a G45 lower, a G45 longslide if you will.

 

I don’t have either one, but I do have a couple 19’s.
I will probably buy a 47 just for the fact that I can then have a 45, 47, and a 49.

 

There you go... Ladies and Gentlemen, we have a winner 😁

 

Or… hear me out.. just get a 19 and a 45/19x and maybe even a 26, Then you don’t need to swap parts, and you have 2-3 blasters that use the same holster. choose your grip size and capacity by the needs of the day

what does a long slide give you that your interested in? Serious question.

comp? Get a 34
Sight radius? Meaningless with a dot
Ballistic performance? Idk if it matters here

 

Well, if you buy a 47 and a 19, then you actually have a 45, 47, 49, 17, & 19.

 

The 47 is really identical to a 17 (dust cover length and G5 innards are the only differences).

Slide length and height on the 47 and the 17 are identical.

The 45 is the same height as the 17 and just has the 19's shorter slide.

The 47 came into being for the BP because it wanted to be able to swap a 19 slide on to a 17.

 

I carried a gen2 G-23 both on duty and off after carrying a Colts Commander for 15 years as
a LEO. I changed departments and had to switch to a Glock. The 40 in a smaller pistol felt good to me, and it was. I carried it for 5 years and retired, and continued to carry the G-23.
I recently started carrying the G-43X and have enjoyed it. Not long ago I picked up a G-45, and carry it mostly working a security Detail at Church. I still carry my G-23 sometimes.
Like all 20 years in LE, I never had to shoot anyone Thank The Lord.
I also worked 10 years as a Nuclear Security Officer, at a Power Plant.
We carried The Beretta 92SF, I never liked the 2 speed trigger on the Beretta, but they were dependable, and seemed to last forever.
I have several pistols now and like them all.
I just don't get to go the range as much as I used to.

 

what is the point of a 17 length over the 19/45 length slide? Serious question.

 

Good point.

As others here have correctly observed the sight length distance is mooted if you use a red dot and the velocity increase is minimal.

I cannot believe .4" decreases muzzle flip to any measurable degree.

I have several compact long-slides in 10mm, 40 & 9. Couple Steyr L models, a pair of P80 compact long slides. A couple of the large frame poly Tanfo's that came out in the late 2000's, 2010 time frame. And a Frankin Canik C100 with a P120 slide on it. I like the balance of a compact long slide. The impulse or felt recoil. That slight difference I find more enjoyable. Not that a compact is an issue. But the slide is longer therefore heavier. The barrel is longer so there is more time for power to burn. I've always thought a 5" felt smoother than a 4.5. And a 4.5" felt a bit smoother than a 4, so on and so forth.

 

I am not sure where Glock is going with these different configurations, but maybe someone could work up a mini matrix where the combinations were laid out. Just as a couple of examples, the 45=19/17, the 19x=19/17, the 49=17/19 and so on. Just thinking out loud.
