No Striker TYPES my Son has a few he's a Glock guy, he shoots well enough but needs to pratice more than he does. The Glock people say that you can't shoot lead, jacketed bullets are expensive for practice, I don't like plastic guns anyway. As far as heavy goes I don't mind weight plastic guns recoil more making follow up shots that much more difficult. I carry so much its like getting up and putting a watch on I DONT GIVE IT MUCH THOUGHT EXECPT THAT MY PERMIT GOES IN MY POCKET THEN THE GUN GOES ON TO THE POINT OF OBSESSION
