Grips for A100 Frame - Threat or Menace?

[edlmann]

I keep reading conflicting accounts on what grips can be used on a Mark I or Standard pistol with the A100 frame.

Any definitive information out there?

Due to frame changes, you have to get a cooresponding grip panel type. They wore out the stamping dies for the frames, so they made some changes, to the position of the mag follower button. (Swapped sides on it.) That caused them to move the screw hole position.
Chad Hiddleson's book is an EXCELLENT resourse for this info.

bottom line, you can tell at a glance and not even have to pick up the gun,,,,,,,if the BOTTOM hole, is LOWER, on the left panel, it is an A-54 frame, (early gun) if the hole on the bottom is LOWER on the RIGHT panel, it is an A-100 frame, (later) easy to tell, and yes, they are interchangible as to the upper receiver, so this may NOT tell you the vintage of the gun , and its serial number...we see them swapped around ,all the time, so one has to "know their grip hole locations"...........,mainly at the bottom....obviously, the Mark II will have cutouts for the slide stop lever on the left panel at a later date, but this is another story.........

. . . on what grips can be used on a Mark I or Standard pistol with the A100 frame.

. . . the Mark II will have cutouts for the slide stop lever on the left panel . . .

Is there an issue with the hammer pin?

if you are asking about putting Mark II grips, on a Mark I or the early 'standard' autos, yes, the cutout in the left grip panel, will allow the upper pins in the grips frame to wiggle out and to the left, and shift "parts" off their 'axis'...one has to put a "filler" (spacer?) in this cutout area.....
