I have a stainless Wolverine 209, have the opportunity to purchase a Disc stainless at a good price. I've never seen an original Disc model, am wondering if these use the same ignition system my Wolverine uses? If so, other than a longer barrel, i can't see I'd be gaining much with the Disc, my LK 93 Wolverine is a good shooting rifle to at least 100 yards.
