i am looking to pick up this revolver but i need some more information that I am having a tough time finding. when were they made, if it was over multiple versions such as 629-4 629-5 or 629-6, would they have the endurance package, can they handle full house loads, how durable is the laser etching on the cylinder and will it wear off easily from repeated holstering, etc... I would appreciate any insight on this model that anyone can lend, and it would be great to hear from people who own it as well. Also, does it have the IL?
