I have a lot to learn about firearms. The one I bought is a Kahr. I read several reviews of it and learned that it’s a pretty nice gun for a beginner. And it’s small so it fits my hand very well. I’d like to own a S&W someday.
Eye and ear protection are very important. The 32 dB foam ear plugs work well, but there is some additional value in the variety that cover your ears. It limits bone conduction AND it protects your ears from flying bits of lead. I've had a couple trips to the range where I just used the foam plugs and got nailed on the ear with a piece of flying lead. That stinging feeling coupled with a wet, sticky feel on your ear is a good clue that something's not right. A long sleeve shirt with a high, closed collar will keep hot brass from burning your arms or going down your shirt. A ballcap with a bill will keep the brass from rolling down your forehead and getting behind your shooting glasses. Lessons learned from many hours on the range.
If you shoot metal spinners, make sure they are the correct weight for the caliber you are shooting. Also, make sure they are at least out as far as the minimum range specified by the supplier. A ricochet back onto the firing line is unwelcome and dangerous. Just because you're doing things right doesn't mean the person next to you is playing safe. Always wear the hearing and eye protection when on or near the firing line.
