I have gone through most of the posts on this board about the CM22, most seem to indicate a feeding problem after some use. But most of those messages were more than a year old, so I am here to see if any opinions have changed.
Are the CM22's issues possibly caused by lack of maintenance? I currently shoot Pardini, and it is fairly forgiving, I clean my gun maybe every 2 months or so. But I heard someone who has a CM22 says she cleans hers every few hundred rounds. Can this be the solution to the feeding issue? If so, I suppose it is annoying, but not fatal.
There was also the issue of the light strikes, after all this time, has anyone found a common reason for this?
Thank you all!

persisting problems
I have owned and used a -"steel-version" CM 22 extensively since late 1999.
During this period the gunshop has supplied me with new magazines, as the early ones caused a lot of trouble.
There are however still some problems. The recoil spring of the CM 22 has a strengt that is apparently designed to protect the gun from damage from use of high speed ammo, if anyone would be silly enough to fire that stuff in this top end match pistol.
But this (too) strong spring brings problems with moderately powered match ammo. The recoil impulse is not suffisiently strong to cycle the heavy slide, and the cartridge case of the fired round is sometimes fed back into the chamber, or "stovepiping".
The CM 22 features a very heavy bolt. Which, in combination with the heavy duty recoil spring, makes the cycling of the gun unreliable with moderately powered ammo.
I recon the factory is just about to start to make the bolts lighter, to solve this problem.
Yes, I know there is a buildt-in recoil buffer arrangement at the rear end of the recoil spring. But adjustments made to this buffer have not brought any decernible improvement to the cycling of the gun!
When this buffer is adjusted (retracted) fully, as it should be for mild ammo, the screw, which fixes the barrel/slide combo to the rear frame, will interfere with the recoil buffer. This screw cannot then be torqued down sufficiently, cause the tip of the screw contacts the buffer. The screw will then often loosen up during the firing of less than a box of cartridges.
Filing off the tip of this screw reduces the problem.
The trigger unit of the CM 22 is probably the best part of the gun. One problem has occured though: the screw adjusting the 2. stage weight will slowly unscrew, and the result is a pull slowly growing leighter. This can be cured with tread-lock. Most other adjustment srews of the CM22 have set-screws. But not that one.
The "steel" CM 22 has too much mass up front, giving it a odd balance. I do not favor this balance for slow fire.
And the "alu"-version is too light, and additional weight(s) must be mounted.
And I do absolutell not favor the necessity of using a screwdriver to adjust the rear sight of the Morini guns!
