Range shooting is one thing, Dave. You're expecting and ready for the shot. You're not ankle deep anchored in mud, gun in the crook of your arm, checking your watch when the bird comes flying in over the grass. Well, you get the idea. Hunting is not the clean environment that games on the range are. Neither is combat, I would imagine.
It may be that I've used the tang safety on my old double until they passed the steel shot laws, then got a Mossberg with a tang safety. I'm just so used to it. But, I really prefer it to the crossbolt on my Winchester which requires cradling the trigger guard in my hand while I reach under and kick the safety off with an index finger. The tang, I can kick it off with the thumb as I shoulder the weapon, much faster and requiring much less fumbling around.
If I see the bird coming and have time to kick that safety off before the bird sets into the deeks, I have time, but sometimes, many times you get surprised.
Yeah, cold wet thumb shoving a round up into that 870 hurts like hell when it pinches. Many times I've yanked my thumb out before the round clicked into the magazine, cussing, and it shot under the shell elevator tying up the gun. I'd have to dig out my pocket knife and work the shell back into the magazine. Do it with heavy gortex/thinsalate gloves on and it pinches the loose end of the glove finger and you have to work it down and get the glove out, irritating. I've found neoprenes work a little better, but not always effective, either. D
Duck hunting is cold and wet. I don't shoot skeet, I couldn't care less about clays, I hunt ducks. These are birds that live in the marsh an the season is in the winter when, even in south Texas, it can get cold. That's what I do with shotguns, I hunt ducks and geese. Okay, doves, I hunt doves, too. The crossbolt safety is less of a pain on doves because if I ain't half asleep, I usually see the little buggers comin'. And, the shell elevator is no big deal because dove hunting is in September and October when it's 90+ degrees down here and my thumb isn't numb from the cold and I'm not wearing gloves.
I may get a BPS someday, but in 20 years I haven't even close to worn out the Mossberg. Figure I may hunt 10-12 days a season, maybe, fire maybe 15 rounds average between geese and ducks. Even if you do a couple of dozen dove hunts with the same gun, how long is it going to last at that rate even though I'm firing 3" magnum heavy steel shot exclusively in the gun? I dove hunt with either my Winchester or one of my side by sides, only use the Mossberg for waterfowl. The Winchester is a gas operated auto and that's nice on my shoulder when I'm burning up rounds on dove. Most shotgunners, hunters anyway, don't see 250K rounds in a lifetime even if they shoot a round of clays now and then. We're not all Olympic trap and skeet champions. Most of us just shoot birds.
Actually, if I replace that 500 for waterfowling, it'll probably be with a Mossberg 935, tang safety, ya know. Crossbolt safeties suck. Did I mention that?
