My buddy and I shoot a Colt Python .357 and S&W Performance Center 627 8-shot .357 respectively and we've both been experiencing primer ignition problems with factory loads (blazers, lawman) and our own reloads). The problem is usually in double action firing for the both of us (every 2-3 shots) and sometimes even in single action mode.
(1) There's a "strain screw" on the front of my grip strap of the PC627 that screws into the mainspring of the revolver. Will tightening this "strain screw" increase the weight of the double action pull and solve the problem ? What is the purpose of this "strain screw" ?
(2) My friend has replaced (by himself albeit) the firing pin, firing pin spring, and mainspring of the Colt Python, and problems still persist. Any one have any suggestions ? We though it may have been deep primer pockets in our reloads but the problem exists even with factory ammo...
