I put a new Hogue Handall on my XD before going to range Saturday. This is only me second trip to the range since I got the XD. Even thought the handall feels better, I think its hurting my shooting. I was shooting consisently low all day. Its got to be something I'm doing and I'm worried that the handall may be affecting the way I'm holding the gun. has anybody else had this problem or am I doing something else thats causeing this. Please help.
