so i put about 100 rounds through a glock 22 today and i must say i was truly impressed! no other pistol has fit my hand quite as well or had such a smooth trigger pull! the trigger pull was just right not too heavy or too soft! well no the dilemma! I would love to make this my first pistol (20 days into my wait for ltc-a) but i dont know if i want to buy a used police pistol! are there issues i can expect if i buy a glock with a lot of rounds thru it? also someone suggested a smith and wesson sigma saying its a glock knock off but how close is it because i have shot an m and p and it was nowhere near as nice as the glock! well any advise would be appreciated! thanks
