So I was planning on sending my EMP to Wilson for some custom work however it seems they will not work on the EMP. So it looks like I will be using the Springfield Custom Shop. Can anyone answer any of the following questions. 1. The don't list a round "butt" option on there work order, anyone know if this is an option. 2. I would also like to have the barrel deep crowned but didn't see that as an option either. 3. Will the install user supplied parts? IE, thumb safeties, Triggers, ect.? Thanks in advance for any info that you can provide.
