Im looking at it and the way the bolt strips and feeds the rounds into the chamber, with a round fully seated, i can still see brass so there is no locking like on a ar-15 or akm where the bolt head rotates and locks the round into the breech, i know its not a open bolt cause it is hammer strike fired. i am guessing its safe this way, but seeing brass worries me a little bit kinda like a glock 40 unsupported barrell, is this the intended way of chambering and firing a round with this gun, im fairly fairly new, been reading ps90 p90 stuff for a long time, just finally got my hands on a ps90 to play with myself and was looking at what all does what, so in simple terms, am i supposed to see the rear of the cartridge when its seated fully in the chamber prior to firing. thanks for any info
