Less difficult to rack? Fine for me, but my wife loves the gun and has a problem racking the slide. Someone at the range let her rack the slide on a glock 19 that probably has 10000 rounds through it and she liked the ease with which she could rack the slide. Also, I have a 4.5 XDm. Would the 3.8 be different due to the different recoil spring design? Thanks in advance.
