Dovetailed ejector stop
 

I'm aware Parker barrels fitted with extractors have a screw-stop placed into the lug of said barrels; designed to interact with the extractor rods. What about Parker ejector guns? Do they have that same stop-screw to protect the ejector stop plate and its dovetail? (unlike the Repro's)

No. There is no screw in the barrel lug of ejector guns. The stop plate in the rib extension is the sole stop point and retaining method for the kickers.

Thanks Brian. That surprises me. I presume the Parker can suffer similar wear to the dovetail as the Repro does. Think I'll be making some mods to barrel lugs in the near future.

And for that very reason it is always ill-advised to dry fire an ejector equipped Parker - not because you might break a firing pin - you won't - but because without the resistance of empty shells or snap caps you stand a dramatically increased possibility of damaging the dovetail in the doll's head, the stop plate, the screw or the threads in the doll's head for that screw.

I had a Repro come to me with a little up/down movement of the stop-plate. A closer look revealed the bottom of the dovetail required a little peen to tighten the plate up. I also didn’t realize, until closer inspection, that the plate relies upon the close fit of the screws head and the hole in the stop-plate to restrict up & down movement. In other words, the screw doesn’t bottom out on a shoulder.

Unfortunately, the design isn't conducive to linear wear. Rather, it'll worsen rapidly once the plate develops a little movement. Neat design but poor execution IMO..can’t believe Parker didn’t use a stop-screw. That little screws head should be kept flush with the extensions face, at all times, for max rigidity.
