wife loves shooting the 22 mark3. Hates the cz 9mm as its too scary and load. I load titegroup at 3.5-4.1grains with a 124round nose. Could I put like 1gr or less to get it down range at 25yards?
 
Start working your way backwards with the amount of powder used until the gun won't cycle anymore or the accuracy goes all to hell. It will still be louder then the 22. I also have the 22 Mark III and a CZ 75 9mm.

If she has proper hearing protection the noise level shouldn't be a factor no matter what you shoot. Most people who have issue going from a 22 to a 9 is in the fact that their grip is poor. Teach them how to hold the 9 and it won't jerk around so badly on them.
 
You could go with a light main spring - 11 pounds or so, then cut a couple coils off if it. Then just play with your loads so you are still getting positive functioning. In theory I do not see why you couldn't get a 124 grain down to 750 - 800 FPS. I would not go below that as then you are getting into potential for bullet stuck in bore. I have not played with this though, I am just extrapolating from what you can do with a 38 Special from the bottom end in regards to how slow you can go. That being said revolver vs auto.
 
1grn or less would barely cycle the pistol, much less be accurate at 25 yards.

Look for data that has been tested for min loads for the 124, then go down from there. But be careful
 
There are two factors - noise and recoil.

Noise - foam ear plugs plus ear muffs. Good protection, anyway and will reduce flinch.

Recoil. Tiegroup is the rigjht powder, but 124 are the wrong bullets. Buy a box of of plated 147s (I got mine from Budget Shooting Supply). Load the 147 s from 3.2 down to 2.5 and see what cycles the action and shoots well. Be prepared to scrap the ones that are too light, so only make 10 of each for your first test.

One of my 1911s is most accurate with 3.1. Being a heavy gun, recoil is gone.
 
actually a lighter bullet would reduce recoil, I used to use a 115grn rn with my 38super, and recoil and muzzle flip was minimal but that was with a HOT load going at 2500fps. That would give major in IPSC before they didn't allow it anymore due to people killing their guns and loading it unsafely.

I used IMR 4756 with a 115grn rn copper coated bullet. I will not release the primer or powder charge for safety reasons.

You can use the 115grn, and less powder and that would be a nice steel challenge like load. I find the heaver the bullet, the more the muzzle flip.
 
When I was working my 9mm ammo down to a 130 power factor for IPSC I found that I began to get stovepipe jams when shooting outdoors on cooler days. Even in warmer conditions I found that the ejection was weak and I'd get the odd stovepipe jam. The cure is/was the next lighter recoil spring. I never did get around to ordering it but that's another story.

But that was with the loads sitting in the middle lower end of the regular loading data and the 125gn bullets running at around 1050fps. You are looking to drop right off the lower end of the data altogether. It simply won't even begin to cycle the action even with the next lighter recoil spring. And that's even if there is enough pressure to burn consistently at that low a powder amount. And if she's that sensitive to recoil then even the lighter loads and the second lighter spring won't do the job either. It'll still be pretty snappy.

If she's enjoying the rimfire why upset the apple cart? Just let her shoot the rimfire and enjoy it. If SHE, rather than you, is keen on center fire and just does not like the 9mm then maybe you need to get her into revolvers. Then you can download to her heart's content as long as the bullets make it out of the barrel. A local cowboy action shooter is currently using 2.0 to 2.2gns of Titegroup in his .38Spl loads with 105gn bullets. I've heard popcorn going off that is louder. But he's actually gone too far. The pops from his guns are inconsistent in sound. I'd be willing to bet an E-beer that it's because there's too little chamber pressure to ensure consistent burning. His loads all make it out of the gun but the sound of them is rather odd and highly variable. Don't go that low. And given the different case volumes your idea of 1gn of powder is pretty well down there and in line with what he's doing.

It's all acedemic anyway since that light a load won't do more than bump the slide back a bit. It may or may not even eject the empty. And I'd bet an E-beer again that it won't get the slide back far enough to pickup the next round eve if the empty does manage to squeak out.
 
I've played around with a few de-tuned loads in the 9mm. I've went slightly below starting loads with titegroup with good function, and decent enough accuracy. Clays is a good powder for lighter loads as well, but for me, accuracy fell out the window going below the minimum (with Clays). No recoil though, was like a mean 22 rimfire.

One thing I'll mention, although it was a different caliber (38 S&W), was Titegroup getting extremely erratic at extremely low charges. I didn't know where I should be, so I loaded various charges, like 1.5-1.6 grains with a 124 grain bullet. Anyways, over the chronograph, one would clock say 500 fps, then the next 365 fps! Nothing like seeing your bullet on its way to the target. I honestly don't know if it would do the same in 9mm, but it was amusing.

I type pretty pokey, so I see another mention of Titegroup being erratic down low mentioned already.
 
Recoil can be measured or calculated.

Perceived recoil is something else. And what matters is what your wife perceives.

With a fast powder and heavy bullet, loaded as light as possible but still cycling the action, the perceived recoil will be less than a lighter bullet because the heavy slow bullet spreads the energy out over time.

Perception is a function of both energy and time. A push and a punch might have the same energy, but only one hurts.

Try the TG with some heavy bullets.
