I have one "Perfect Repeater " with a raised milled rib, my Pigeon Grade M12 Trapgun mfg. 1946 era. I have 4 M12's with the solid matted rib- (1) 3" Heavy Duck 30" F-- 28" field grade Mod. choke, 20 gauge 28" Mod and a 28 ga. Field Mod. choke. I only have 1 remaining WRA pumpgun with a plain barrel for comparison- M25 28" Full--This is my Numero Uno "Barnyard gun" the one I load up fully with Express No. 6 for evening CQC with raccoons, fox, woodchuck, even coyotes- from point blank out to a measure 38 yards distance, thatWRA pump with either No. 6 chill or 00 buckshot is devastating, and like all WRA pumpgun made prior to 1964, 100% reliable. And outside of that Full choked M25, the Pigeon Grade Trap has the tightest patterning Full choke in a 12 bore scattergun I have ever shot. RWTF

This is another prime example, Fox, of your off-topic, anecdotal posts that contribute nothing to the subject matter. We all know you're a good guy and have stories to tell, but at least consider the subject matter and whether these asides you post say anything worth hearing. Thanks.
To the topic, I like vent ribs on sxs's if they are aesthetically pleasing. I give you a good example (I love this gun):
