Yes, it does make it very difficult for a regular person to "finish off a collection". I have never been able to do so regardless as my collection focus just expands from say... one model of a particular revolver to every finish and barrel length. It really never stops until you either stop it, you are forced to stop, or you just get too old. Honestly, I have not expanded my focused gun collection in a couple years due to economic considerations. That doesn't mean that I haven't purchased any new firearms. But they have slowed down as well.
