hmmm...
If you have shot the CZ 75B 9mm and liked it... CZ makes an identical gun in .22 LR... The CZ 22 cal is expensive, but offers outstanding quality and a mostly steel frame and slide... The aluminum 'slide within the slide' is brilliant, and works great with regular cleaning. Yes, CZ also makes a 22 cal conversion kit for the 75B 9mm... however, the last thing you want to be doing is changing slides at the gun range, so buy two separate guns.
My GSG Tactical .22 LR is on order, and will arrive once I am home from my holidays... My favorite online dealer is holding it until I get home... nothing worse than a parcel waiting at the post office... in this case, my gun. I bought the GSG because of it's unbeatable price, 1911 frame, and decent quality. 4 mags and the gun, all for under $500 was awesome... as it is nothing more than a fun plinking gun, shooting dirt cheap .22 LR... and 4 mags are necessary as one shoots freely and fast with cheap .22 ammo.
I had sold my 75b .22 ... and then realized I wanted a .22 plinker again... for cheap shooting, and introducing friends to hand guns. I honestly believe 9mm is too much power for a friend who has never shot before. Taking friends who never shot to the range is important, especially the hell left wing bent type who got nothing but garbage to say about guns... until they finally try shooting a handgun, or a round of trap with a 12 gauge.
Cheers
PS I wish a Canadian dealer sold a 1911 Titan frame sized .22. That really fits my hand well. I purchased a titan 1911 .45, threw on Crimson Trace Laser grips, and it is my home defense choice.

& yes... it is a legal Canadian version, with the 4.25 inch barrel sticking out, past the frame.
Final Thoughts
There are action shooting sports like IDPA & IPSC that do make handguns fun, but both sports require large round counts. My own experience was that handguns get real boring, real quickly.
If you are fortunate to belong to a decent range and can shoot trap and / or skeet, then I strongly suggest stop by the trap range when the members are shooting, and ask to try. You should have no problem finding someone willing to help you try the sport... Believe me, blowing up clays with a 12 gauge shotgun is a stupid amount of fun that most ranges can not match with handguns. Indeed, most ranges would even have multiple plate set ups to knock down.
