I have 2 repro cases ,1 came with my 28ga, the other I purchased with no gun. Both are 26 inch and only 28ga snap caps fit in both.I tried to put 20ga snap caps in but no go.

It appears your case is a 20ga, 28" barrel, pistol grip case. The pistol grip tucks in just like the toe of the buttstock. If there is no window for the pistol grip to tuck into, then it's for a straight stock.

Would you please post a pic of an Emmebi-made Parker Reproduction case that was furnished for the standard DHE and BHE models that were intended solely for straight grip guns without the cut-out window?

Thanks for posting the pics, David. Are these both your guns?

I realize this is a bit of minutiae, but those snap cap holes of both cases appear a bit funky. In your bottom pic, are those 28ga. snap caps in a 20ga. case? (It appears the caps themselves are short and appear small in diameter compared the the holes).

Below is a pic of one of my 28ga. cases that has a 28ga. and a 20ga. snap cap riding side-by-side. (Notice the snap caps bottomed out leave about 1/8" above the felt).

No, they are not. But they represent the two style of cases (pistol grip & straight grip). I've have & have had both over the years.

Also, I've have had and/or have 2-straight grip & 4-pistol grip guns that were mated in the proper cases, including snap caps.

Also, who knows how accurate the mating of the guns & cases were from PRS were, or the retailer, or the used gun store mismatched them to a case. And/or owners who own severial & decide to sell one & pulls it from the safe & gets put in the wrong case.
