Query: nothing but troubles

This is my second PC roofer. I wore out the first one in about a year. Home Depot lost it while rebuilding it. To their credit they gave me a new one. That was 8 months ago. the second gun jammed more than the first and gave up the ghost 2 weeks ago. I am a carpenter by trade and only do 150 or so squares a year- not abuse by any means. by the way I'm ordering a Hitachi this week
