I bought a XDm 4.5 in 9mm the other day. I ordered a Blackhawk sepa CQC for it and it came in today. I like the serpa holsters but on the XDm it has a much tighter tolerance in the sight channel. I'm thinking about getting some truglow tfo's for the gun. My question is do the tfo's sit higher then the stock sights (front post only needs to be considered.) any one have the same Combination of sights and holster? Or if AJames is around do you have any insight?
