yak-9k have muzzle brake, like and small series of laggs/yaks-7/il-2s with SH-37 - ie here attached pic with, apparently, exactly lagg with sh-37 from tests'42 (by the way, in reports noted what in compare with planes with ns-37, planes with sh-37 were much more stable when firing in flight, and if firing bursts too) - but force of recoil of ns-45, like and of ns-37, was very serious, in many books written what optimally firing by short bursts (2-3, sometimes, max. 5 shells) and accuracy/recoil very depends on speed of plane...

and in fact, i read lot of mentions about recoil on land/in air, but now can remember only what written about yak-9t one of best soviet aces, Vorozheykin -

Можно попробовать? - спросил я Герасимова, показывая на кнопку управления стрельбой пушки.

- Давай! - и Николай Семенович подал команду: - От самолета! - и пояснил: - Он при стрельбе на земле, как необъезженный конь, брыкается и может лягнуть.

Я нажал на кнопку. Всполохи пламени сверкнули перед "яком". Грохот ударил в уши. Самолет от сильной отдачи на метр отпрянул назад. Ого! Действительно брыкается.

by the way, further, he mentioned about HE shells with self destruction -

А где же шары? Наверное, проглядел. И я, еще дав два залпа, всматриваюсь вперед. Цепочка хвостатых разноцветных шаров вспорола синеву и где-то далеко-далеко разорвалась. "Значит, снаряды, чтобы не падать на землю, в воздухе самоликвидируются", - подумал я, разглядывая рябинки в небе от разрывов.

well, after first combat tests'43 pilots wanted other type of self destruction, but i not found clear information, this was realised or not, like and about new AP shells, so, at this moment i only can say what self destruction, apparently, was after 9-12 sec after shot (or after 3000 meters, information very different, maybe, again need to check book of nudelman)...
