New guy from the OKC area. I have a 642 serial # DCB4664? that I bought about 4- 5 yrs ago. In no way or fashion am I gun expert so I decided to join the forum to learn more about the gun I have. I would say I have less than 100 rounds. From what I have read, the recommendation is to dry fire it to help with the trigger pull. I do think its a bit tough. I have no plans to alter the weapon besides cosmetics. Maybe the grips or polish the outside to the barrel cylinder. The few times I have fired it I enjoyed it. I purchased this weapon because it was small lightweight and I did not want to mess with a magazine. Keep it simple. The few times I have fired it, I enjoyed it. Thank you in advance for your feedback.
