IMHO all potential personal gun sales should be first and foremost judged by two criteria.
- How much I honestly like it... or not.
- How easy and (relatively) expensive it would be to replace it if I regret the decision.
Regarding the second criteria, I would be much more hesitant to sell a Steyr GB than a Star 30PK, assuming I dislike them both equally. (I don't really own either; this is just hypothetical.)
BTW is this handgun a Star?
