That sounds like you got a good deal for OTD!
I would save my ears for absolute self defense, though. Shooting without protection can ruin your hearing! I wish I still had all of mine! I use earplugs AND "muffs" rated at -31dB protection. I just got back from the range where I shot my PM45... 200 rounds of 230-gr FMJ and 6 rounds 230-gr Gold Dots Short Barrel.
My ears always ring... tinnitus and high frequency loss... more HF loss in the left ear, so my direction sensing for beepers and alarms sucks.
Take care of your hearing.
