I keep my Spartan loaded and on safe. No exposed hammers for me. All that crud about springs is total unadulterated bovine excretion. I've left my old SxS cocked for 40 years and it still goes bang every time. I got my Spartan in 20 gauge for the weight and in difference to my poor old shoulder. I hunt doves with it, does hiking duties now and then as a combination gun, one slug, one shot load. It's a great camping, truck, whatever gun, hard to beat. It ain't real pretty, but it's rugged and it works. The screw in chokes assure it doesn't just sit around.
It's a fun and effective dove gun to 35 or 40 yards with a modified barrel. I don't like the full choke, pattern's too tight for doves. I usually choke it I/C-Mod. Out to 25 or 30, I/C is DEADLY on the little buggers.
The gun is light and changes direction well, a good thing on doves. It's quick to the shoulder for upland game. It swings a bit whippy and needs concentration on those long, smooth sustained leads. That's my one criticism, but speed and smooth swing are always trade offs in wing shooting. I generally shoot about as well on doves with the thing as I do my Winchester 12 gauge auto, which I like, also, for doves. The long, high shots that I miss with the Spartan tend to be countered by the close in buzzers I manage to get on and swing quick with that I'd miss with the mod choke and slower swing in the 12. If I concentrate with the 20, I can swing smooth, just takes some concentration. Makes ya a better wing shot.
Suit yourself on the hammer thing, but hammers SUCK in the field. If you're REALLY worried about it, I have YET to try this, but I hear you can leave off the fore stock, snap the gun on snap caps, open and replace the snap caps with rounds, close, reinstall the fore stock, and the hammers will remain un-cocked. I don't know, however, if they're at rest OFF the firing pins or not. I haven't got the snap caps to try it. I will, eventually, make some snap caps by removing fired primers of a couple of empty cases and filling the hole with shoe goo.
