Para's finish is known to not be very durable. If you are going to carry the gun anyway, I wouldn't worry about it.
I have guns I carry, and then ones I never holster - I baby the finish on the ones I do not carry. On the others, I do not care.
However, I would use someone like CCR Refinishing if you want a better finish. But, as you stated this is a carry gun, I think its a waste of money. You will be surprised how fast the gun will wear thru holstering and carrying.
