Ive just put together a caspian pistol that ive been working on!!! When i put the frame,slide and Barrel together they lock up fine and require a little force to lock up all the way , the pistol is almost impossible to cycle with the bare force of my hand because it locks up and the barrel acts like it does not want to unlock and requires a gentle slap to the front of the slide with the palm of my hand in order to unlock it out of battery. Ps. The slide to frame fit is not too tight to be of any problem . Any help or advice would be appreciated!
