The SXS Shotgun seems to
be have been the bastard step child in CAS....
Players will spare no expense it seems , tuning or having their rifle raced and the revolvers tuned...but the 3rd gun in the quiver often was a DIY , buff & polish and a spring bob of sorts.
Reason I suppose, is A . Stoegers , Baikal's etc. were 1/2 to 3/4 the cost of the rifle. B. plentiful old Grade , double box lock SXS to
use...I:E: Fox 311's , Foremost , Stevens , old Ithaca's in almost every closet....
So many were pressed in to CAS use.
The Gamers embraced the 97 pump. 1897 is past the golden era of the "OLD" west but fairly it is under the 1898 CAS cut off date.
So perfectly approved....
But to your, question.... Yes, Stoeger, Check out the Deluxe SS model about $600 , there is sweet spring kit available
from Palo Verde

Baikal made a true exposed hammer ( not talking about the cocking lever model)
