Been considering making a Glock 32 my next Glock purchase. I see that it's about the same size as my Glock 19, my favorite EDC of all time, but admittedly, I have no experience shooting one. I check every time I go to my local range but they never have one to test out. I know the ammo is more expensive but the ballistics look good and from what I've researched on YouTube, which makes me an expert as we all know...lol, it doesn't look as snappy as I've heard, The .357 Sig looks like it's happy place is 125 grain and looks about right. So, I was just looking for info, stories, pros, cons of the .357 Sig Glock 32 as compared to a G19. Thank you in advance everyone, it's much appreciated as always.
I actually took the same plunge recently. With the G19 being my carry gun and main training platform for years, I liked the idea of zero learning curve to the gun feel, handling and concealment with some potential benefits to barrier penetration and faster traveling bullet for benefits at longer distances. I have seen 357sig outperform the other common 3 calibers in vehicle ballistics and have improved my longer range ability so was looking at potential improved ballistics and accuracy at distance. This was in the spring too before the mall shooter got everyone pushing past the 3 yard line.
I went into this project understanding that this move had a high potential for becoming nothing more than expensive experiment I would look back on and shake my head. I have been comfortable carrying a 9mm and still am. But I was looking to explore options and some of the posts here got me wondering. My testing is still in progress but I am liking it so far, aside from ammo cost.
What I know so far:
The G32 is the same external dimensions as the G19 in every way. I'm one with the gun like the 19 immediately. Holster compatibility, etc is perfect.
The G32 recoil isn't bad at all and is actually quite fun to shoot, uncomped. I would say it's about on par with my 40cal g23, maybe a touch more and definitely more than my g41 45. Possibly the funnest pistol caliber I own to shoot actually, but I can't say why exactly that is over the 40 or 45. Maybe it's the shockwave my neighboring shooter buddy tells me about.

It's a "blast" to shoot and feels like a gun should feel, and definitely makes the 9mm feel like a pea shooter though when I go back to it.
But aimed follow up shots under recoil are slower too. That's just physics. Since I already carry with a KKM comp I started to wonder how much that would reduce times on the 357sig vs 9mm in comparison. In very limited and unscientific testing so far with only my freehand sample size of one, a timer shows I'm consistently slower as expected. Underwood 125gr Gold Dots vs Speer 124+p Gold Dots. I have shot a couple hundred in testing so far but this pic is a decent sample of what I have produced so far.
Is it slow enough to be a real negative though when considering the 9mm will potentially outshoot my brain's ability to respond to input if I'm just throwing rounds as fast as I can get on target? Well that was really my big question and only real potential negative that I'm trying to weigh about the caliber. My thought is as long as I can do .27-.31 aimed splits then I'm not gaining anything by being able to go faster. I get that figure from Reston's info here on reaction times and decision making. I got a lot out of this video and it was the lightbulb that got me thinking about trading shot speed for a round with other improvements, no matter how small.
Side note. Initially I thought my single handed aimed fire would be a lot slower with the G32 and would be the biggest hurdle to justify, since my one hand shooting has become a skill I see as vital and have been working on faster on-hand shooting lately. But in testing I see no difference so far there. Under a timer my problem is actually with managing recoil and getting the red dot sight back in line efficiently, so both calibers are up equally in the .6-.7s range in "fast" one hand aimed fire. Irons are faster in this regard for sure. So I need to improve my single hand rapid fire shooting ability before I will be able to see the effect of the caliber change with a dot.
I have not been out to the long range club yet with it but I do seem to have gotten a lot of nice X groupings at 25y although I haven't actually shot a 100 with it yet either. But that's on me being bad. I suspect it will end up being more accurate at 50y and beyond, but I haven't shot it there yet to say for certain.
That's all I've got so far. Good luck on your decision.
