My Glock 45 is noticeably more accurate than my 17, but my 17 is a Gen 4, so I don't know if that would be true against a Gen 5 17.

Prior to injuring my hand, which sidelined my shooting, it was off-hand, as I don’t use a rest when I practice marksmanship. I shoot almost exclusively at 25 yards when I practice, unless I‘m getting ready for a match, at which point I’ll set up practice stages with closer targets. To be clear, there is a difference between what one is capable of doing and the frequency with which it can be done. Here are two examples shot with my G17:

This is one of the better groups I’ve had with a G17:

I’ve spent considerable time shooting both at the range and here are my thoughts:

First shot: Negligible differences with accuracy. I liked both.

Follow up shots. I was slightly more accurate with the follow up shots using the 45. For some reason, I had much less muzzle flip.

You can’t go wrong with either.

YMMV

Good luck!

As has been pointed out, with an optic sight radius means nothing. That being said, subjectively for me, a G17 has a better perceived balance and less muzzle rise between shots vs a G19X or G45. I shoot a G34 Gen5 MOS better than all other models. I know more than a few professional shooters who exclusively shoot a G45 with great success.

I shoot ny G45 better than all of my other Glocks. But, that is just me. G17 is good shooter too.

Mechanical accuracy of a specific gun, a specific shooter's general capability and a specific shooter's capability with a specific gun are 3 different things.

If you want to know the result of the third thing, you have to test it specifically.

agree here. In all honestly if you took a sample of each model glock and put it in a ransom rest I doubt there would be any statistically significant difference in accuracy across the entire product line. There is obviously variance from sample to sample ( tolerance stacking, etc) I would suspect out of a rest any glock ( barring that outlier that you see every once in a while) will run a 1&1/2 to 2 inch 25 yard group.

my sort of comparison- I was on a military shooting team, and some units we’re complaining about bad accuracy out of some M9’s - I got the chance to ransom rest about 25 of the guns that were claimed to be inaccurate- every one shot less than 3” at 25 meters, most sub 2” and I have little doubt a glock can do the same

That's about right.

But again, if you're concerned with an actual performance result, you need to consider how the specific shooter interacts with the specific gun.

As long as the gun has reasonably acceptable mechanical capabilities, the outcome will mostly depend on how well the shooter can use the gun - same as with pretty much any other tool.
