I am new to the whole gun thing, but the 410 (40 s&w) was the first gun I ever bought too. It has been sitting in the closet for 11 years as "protection". My interest in guns was piqued recently and I decided to get my CWP. I've been to the range now around 10 times and really like the 410.
The range I go to has cheap reloaded ammo and the 410 has yet to hiccup on anything I put in it, including the 11 year old ammo that I bought with the gun.
Still learning alot about guns. I took a handgun safety class that my local gun shop offered and that really gave me a lot of confidence in handling the weapon safely.
I have since purchased a SA XDm in 40. I still like the 410 though and usually take both to the range.
