Thanks Chad for helping me select similar setup to Bill.

I selected Threaded Barrel Closed Cover as an additional characteristic along with RDS cut but I do have a Springfield RDP Compensator installed that extends the overall length of the slide 1 and 1/4" inches and is the same width as the slide both ways. If needed I can provide a picture with a steel rule but I would like the Compensator inside and covered as well. Please let me know and I will provide any information needed. Thank you
