I have 5 winchester 9410, 2 are multi choke, and other 3 are true. All are on SGC. I had a chance to hunt with these in canada and are great slug gun. Great range and effective. we took number 6, 8 shot shells and slugs. these guns are more useful than the write up's i have see in UK. Under UK law 90% of the guns may only be used on range.
I also have 2 winchester 1873, 44 40 smooth bore ( yes on SGC ) and a 44 40 yellow boy 1866 also on SGC. Imagine the fun on private land you can use all these on with SGC. Since slugs are not permitted , buckshot are fun to.
Buy them at any cost. But never seen on for sale under 500 pounds. Paid 900 pound for one from this site.
