I called this morning and Myles responded via email.Try calling them - they are usually very responsive, your email may not have gotten through or they may be backed up.
Ok, that is really good info to know!That's just the way they are I've installed 2 sets of TCAPS both times I had to center up the front.
No big deal use plenty blue locktight and move on . Neither set has come loose and 1 set being on my g20 10mm with my hand loads.
