The 995 is one heck of a lot of fun. Cheap to own, cheap to shoot, and after 300 rounds there hasn't been one problem with mine. PBE, (pull, bang, eject), every time.
These are accurate firearms out to 100 yards or more, so at 30 yards you should be able to shoot the legs off a deer tick. I don't remember what HP says about +P ammo, but 115 gr cjhp should do the job at close range. On another site there was a post about the mercy killing of a large doe that had been entangled in barbed fence wire, the shooter backed out to 25-30 yards and quickly ended it's misery with one shot from his 995.
The original ghost sights were fine on my 995, but due to my farsightedness I replaced them with a contoured 1.5-4x20 scope off an old Marlin 336. Many say that the hologram reflex sights are an excellent sight for the 995 as well, especially for moving targets.
IMO, the 995 is the most practical "Joe Sixpack" small arms urban tactical weapon available. They make for a super HD gun. I carry a Taurus 9mm, having the same caliber ammo makes sense.
I agree that taking the mag base off and installing a block will do the trick. Haven't heard of any 5 rd clips. Would like to hear how you do with your hunting.
