G22 w/ 9mm barrel, Flawed logic?

Would a G22 with a 9mm barrel have less recoil than a G17? I would think that the heavier slide and barrel would reduce felt recoil.

Could I use a reduced recoil spring on the G22/9mm to make the slide easier to rack? It seems like this would counteract the recoil reduction. Basically a G17 that is heavier, and easier to rack.

Yes, this is for my wife.

What makes you think the G22 has a heavier slide? If anything, I'd say it's slightly less weight than a G17 slide. But not enough to matter either which way.

Same for the weight of a 40-9 conversion barrel. We're talking grams of difference, not ounces.

You want lower felt recoil, try some heavier bullets at more modest speed.

So, if the G17 slide is heavier than the G22, and they both use the same frame, then how does the G22 weigh .88 onces more than the G17? I bet the conversion barrel weighs more than you would think too.

The difference in weight between a 17 and 22 is due to the larger diameter barrel on the 22, is my guess.

How do conversion barrels work as far as reliability when putting a 9MM barrel in a 40 or 357 sig?

Can anyone confirm this? I think that the barrel hood/chamber is lighter in the G22, as the external dimentions are the same (exept the part of the hood that enters the notch in the slide. That should be more than offset the bigger hole) Is the G22 barrel thicker than the G17 barrel?

Most say they work very well.

I do not want to hijack this thread, but do you need anything else besides the conversion barrel. I was thinking about it if I did not have to change the ejector. I carry a G32 and I was wondering could I put such in and shoot cheap 9mm practice rounds.

Everything I have read says a barrel swap will do the trick most of the time. Occasionally a 9mm extractor is helpful, and rarely any ejector modification. Typically, most ejection issues can be fixed with different ammo (hotter).

The only issue I've ever had with conversion barrels was using one on my 24, where weaker 9mm wouldn't reliably cycle the action (NATO pressure loads would). Never had an issue using conversion barrels in my 22.

Regarding recoil, the .40/9mm conversion will have less recoil than the .40 because the 9mm load has less than the .40 load, not because the gun weighs more (although a Glock 22 using a 9mm conversion barrel WILL weigh more due to the thicker wall of the conversion barrel vs. the stock .40 barrel)

I've never had to change ejector or extractor when using the .40/9mm conversion although some have.

9mm conversion barrel in a G22?
Caliber Corner

Excellent!!

All I do is swap barrel and magazine and fire away.

Go to Storm Lake

I just got a G27 40-9 conversion barrel from Storm Lake.
Added G26 mags and ran 200 9mm Speer GDHP 124 +Ps through it flawlessly.
In my hands, the gun is more accurate with the SL 9mm than the OEM 40 barrel.

I did weigh the barrels on a digital scale.
OEM 357 Sig--- 3.4 oz
Storm lake 40-9 3.4 oz
OEM 40-------- 3.0 oz

That is all

It is stated here http://glocktalk.com/forums/showthread.php?t=1368242
that the weight of the slide is different, but does not say how much. I hope someone can chime in on the exact differences in weight.

My Lone wolf conversion is 90% reliable with my G23. Fun to play with. I would not trust it to protect my life.

What type of failures are you having? Have you tried to make it reliable, or just settled with it as a plate plinker?

Yes, this is for my wife.
I just re-read your post.
I'm dyslexic and miss a lot - LOL.

The difference in barrel and slide weight is going to be inconsequential IMHO.
The G22 is a big pup, so I'm thinking home defense for your wife?
My Storm Lake 40-9 conversion barrel has been drop dead reliable.
The 40 extractor/ejector has been flawless with 9mm.
If you're looking to reduce recoil further?
You may want to consider a Storm Lake 40-9 extended ported barrel?
That should turn your gun into a kitty cat.

I'm getting one in 357 for my G27 in a few weeks

Another option is to use a reduced pressure reload and a reduced power recoil spring from Wolff for practice/training and switch back when the pistol is at home "on duty".
