Morini 200 barrel weights.

[Jmadhavan]

I am a new owner of a CM 200 Ei which appears to be working fine. I have two newbie questions:

What determines whether one needs to place weights on the barrel? Is it a trial-and-error method or is there a "formula"?

And how does one place said weights on the barrel of this pistol?

Thank you

Weight is a compromise. More means greater inertia = smaller wobble. More also means more fatigue = greater wobble.
This compromise is something you must work out for yourself over time.
Initially, it’s probably best to not fit them. Train for endurance and steadiness and when you’re in the mid-500s start thinking about these refinements.

To fit them (if that’s what you decide), remove barrel shroud and use soapy water to gently slide the weights on. Position them so they don’t occlude the holes.

Thank you for the advice Tony. I tried putting on a weight yesterday, but in spite of applying soap it wouldn't fit. I stopped as I did not want to break the shroud.

I find the 200 to be quite light at the front compared to the 162 - this is how my weights are set up

I have to preface that this is very subjective, but here's what I would keep in mind:

• First train without any weight, as it exposes poor trigger technique easier and allows you to focus on other more important variables first, such as the grip, trigger, and most importantly your own technique (personally I didn't put on any barrel weight until about a year of training)

• Start by putting the weight in the middle of the barrel, then observe how it affects your performance

• As you observe, keep in mind that barrel weight doesn't reduce shake, it slows it down

• The further away from you it is, the slower the muzzle shake will be, but it will also tire your arm quicker

• If it's too tiring after a few shots, move it back until you can maintain your hold, if it's fine, then move it forward a bit and observe

• After a while (this can mean over several sessions), you will see where you can maintain the barrel weight position, and in the future feel free to revisit

Thanks for the advice. I will see how it goes.

The weights don't go on the barrel easily. I coated the barrel shroud and the inside of the weights with soapy water, and it still wouldn't slide in. Does it need a "soft" tap with a hammer? Is there a technique to do this? I am scared to put excess stress on the shroud lest I crack it. I emailed Morini about a week back but have yet to receive an answer.

At this point, I'm convinced the only way involves dark magic

I had the same problem with installation. Comments first, I personally had no interest in placing water, soapy or not, near blued steel. I agree with the weight placement and suggest installing them to the back, away from the front sight until you are ready for the added mass. Once you place the weights, they will settle and firmly attach to the carbon fiber sleeve. They will be very hard to move with the air cylinder in place but can be broken free with rotation once the cylinder is removed. You simply have a better grip that way. You can rub additional silicone on the sleeve if needed when you want to change the position. Don't get carried away with the silicone lubricant, it only needs a thin layer.

Now for the unspoken installation:

Remove the front sight.

Use silicone lubricant on the O rings within the weights and rub a thin coating on the sleeve. I avoided the vent holes.

On the exposed barrel, wrap Scotch Magic tape at the front of the sleeve to build up the diameter so the step from tape to sleeve is small enough for it to slip on.

Remove the tape and reinstall the front sight.

It worked for me. BTW, it's not Dark magic, it's Scotch magic ;)

I hope that this helps. It's a shame that the instructions don't include installation of the weights.
