From a personal viewpoint on the Morini CM22.
I have owned a 'steel' CM22 since 2003 (I think). It has fired probably over 150,000 rounds.
I did compare it to an alloy CM22 (Rapid Fire Model) but will be staying with the 'Steel' version as it recovers better from recoil for me in Rapid Fire. The alloy version tended to 'climb' as I traversed across the targets especially in 4 seconds. (The heavier steel pistol just dropped back into position much faster.) I did not try the alloy version with added weights - it seemed a bit pointless to make it the same as what I already had.
My (and I stress 'my' pistol, so it may not apply to others...) can be a bit fussy in cold temperature (<15deg C) as far as extracting empty cases. Easily fixed with a small drop of oil on the top round when I load the mag. Seems to help makes the pistol cycle faster on colder days. Can also be a bit tempremental after the barrel and chamber are cleaned - I always shoot 10 to 20 rounds after the gun is cleaned before I shoot in competition. (I clean it about every 500 rounds or so.)
Maintenance - I have broken 1 firing pin, replaced the slide return spring twice and changed the silly star headed (torx?) bolt that hold the top shroud/barrel to the frame to an Allen key type bolt.
As for the other adjustments - have adjusted the grip angle once, changed the rear sight gap once, and the 'trigger setup' has not been altered in the last 5 years. (first stage length / weight, let-off etc)
The pistol has never failed a trigger weight check. (I set it to about 1060g when I first got it and it has not changed yet.)
How popular ? In my club, Brisbane Pistol Club, it is not uncommon to see 6 out of 8 shooters using a Morini CM22. There are probably 15 to 20 CM22 pistols in the club. Very handy having the Aussie importer as a club member who can backup the pistol with excellent service and support. (not that it is needed much.) Potter Firearms -

Would I consider a change to another pistol ? No, the CM22 is a good gun for me.
Would I buy a pistol (for Rapid / Standard) with an 'electronic' trigger ? No. Why change a mechanical system that works very well if treated properly.
Would you do more dry firing with an electronic trigger ? Probably not.
How much do you do now ? Twice nothing is still nothing. (or is that is just me....)
I will be strongly recommending my partner (just new to shooting) that she use one of the new CM22s (Steel Frame, Alloy top). It is a bit lighter than the all steel version which is probably better for her in Sport Pistol.
(Fast recoil recovery not quite as important.)
Oh, just one more thing, don't go out and buy an expensive pistol then complain that your $3.00 a box ammo does not work perfectly. A quality pistol deserves decent quality ammo. (I am using SK Standard Plus or SK Pistol Match Special)
A bit of useless information just to confuse things - my best ever Standard pistol score was shot with a Hammerli 208 (heavy barrel weight) and some cheap Chinese ammo that kicked like a mule. 584/600 in 1989 (one of those 'out of body experience' days...) Best with the CM22 - 574 a couple of months ago - mind you, I don't shoot as much Std as I did back then.
