if ur gonna spend that kind of money what are the great significants behind it other than cheap ammo?
....Cheap ammo!!
Last Sunday with my new 22, I left the range because I got tired not because I ran out of ammo....spending less than 10 dollars...
You are best served by one of the relatively inexpensive target 22 (S&W 22A, Ruger, etc...)
The SIG Mosquito is very expensive for what it is...a cheap plastic small autoloader with a short barrel (3.9")...the Walther P22 feels a bit better but it cost even more and the pistol is just too small.
At the next level, the CZ Cadet is a very nice copy of a "real" CZ 75, the Kimber Rimfire is the same compared to a regular service caliber 1911....the question is, is it wise to spend $600-700 for a .22 trainer?? (we are not talking about serious target pieces)....personally, I don't think so....
The Chiappa 1911-22 is the cheapest of the .22 that resemble a regular service pistol......however for a $299 sticker price (real "street price" is a bit lower) you get basically a zinc alloy handgun which is nothing else than a modified version of a blank firing pistol made by the same company with a plastic magazine and horrible finishing....for the same price you can get a very nice S&W 22A (I sold my 1911-22 yesterday...I could not stomach the toy pistol feeling)
Honestly, the only reason I see to buy a 22 resembling a regular service pistol is if your main carry is that specific pistol....and even then, when it comes to actual shooting it's not going to help you more compared to a regular target 22...the recoil, report and just shooting feeling is totally different compared to the regular calibers...
