Generally yes, but WW2 tank logistics was funny like that - sometimes crews wouldn’t have the sidearms they were supposed to have, othertimes, they would have fewer than they expected to. Regardless of whether they had them, it takes the determination to use them, and operating on the presumption that a bunch of Soviets readying anti-tank grenades have just disabled your tank in close-quarters and your only way left to fight them is to crawl out of the extremely visible tank hatch one by one, hoping they don’t plink your head like a watermelon with a volley of rifle fire before you can get a shot off…

Well, surrender probably seemed the more appealing option.
