Should not be a problem but there was another thread where a man bought a walker and the cylinder would not rotate all the way round to line up with the barrel. Both mine do but one was only fired a few times when I got it and the other was NIB. Only problem I had was in the unfired one getting the wedge in and out till I did a little work with a jewelers file. I needed a punch and a hammer to get it in and out the first two times then decided I better fix it. You should be able to disassemble and reassemble without tools.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
