Yeah, mine as well. GBBPs aren't exactly the same as GBBRs, but each GBBR doesn't run identical either. Some are far superior to others. I had a few TM pistols that didn't like hot weather, one that didn't like cold weather, but mostly they haven't been an issue. My current ones are yet to show a problem. I haven't used them in minus temperatures but I have in over 35•.
“REALITY IS LIKE A STONE. TO MANY IT’S HARD AND COLD, THEY CAN’T HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESN’T DO THEM MUCH GOOD. TO OTHERS IT’S STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.”
