Banana's
Like the Frog Man, I too had the Banana grips on both of the guns pictured above. However, when I brought the gun up to fire, I almost always needed to adjust my sight picture. The Harlow grips come up every time with a proper sight picture. It cannot be seen in the pics above but those two sets of grips were made to my specs. The 640 is DAO therefore the trigger is always forward in the trigger guard but the 60 is shot many times as SA which places the trigger farther back in the trigger guard. Curt covered the back strap on the 60 but not on the 640. This extra length on the 60 places my finger on the trigger for a better trigger pull in SA.
