I use P228 and usualy a mp5+heand smoke. Sometimes i go 5-7 with p90.
But i recomende you dont have a glock + mp5 bcuz you lose bullets. They both use the same bullets. So for example you use all your mp5(150)bullets that makes you hve only (30) bulets of glock. Witch is bad if theres more than 2 enemies.
Aks why. Well becouse. if your out off all your glock bulets then you only remain with a knife. whit which yuo wont kill them and just lose.
