I have a 24DL. It is the type that has the barrels soldered together. I don't think I would cut down one that has space between the barrels, It would likely shoot to two different POI.

I had mine cut back to 20 in. I put a Williams peep rear on it at the same time. It is still a bit heavy. It is much handier this way. I carry it on my MT bike and it is much easier to get it out of the scabbard now.

I sight it in for the .22WMR 40 grain loads,1 in high at 100 yds. The 20 gauge barrel hits about 6 in left at 100 yds with the same sight in. Out to 100yds I just hold on the edge of the front sight.

While I had it out of service I sent the barrels to Mr. Orlen and he put in threading for the Colonial chokes I use in my Ithacas, installed a modified choke and sent it back.
