I noticed Cylinder-Slide states they're backed up ~18 months
I noticed Cylinder-Slide states they're backed up ~18 months, if that's of concern; whereas I couldn't find anything on D&L's website regarding its back-log.
I can imagine within 2 years, you'll have a customized revolver modified to your liking. Perhaps, if not done so already, take some "before" pictures now before the handgun gets sent off for perhaps 18+ months.
