A Powder River kit greatly improved my XDm in .45. Good stuff from them. It's is a shame we have to add aftermarket parts to these guns to make them acceptable. Maybe that is what makes this fun for us and keeps creative aftermarket people in business.
Shield, Apex
Springfields, Powder River
Ruger, Volquartsen or Sweet Pea
Browning and S&W Victor Tandem Cross
etc.
