Absolutely...get some good reloading stuff. Ammo will cost you a third of what it does for store-bought. But, semi-auto pistols throw the husks quite a ways off, and I find that aside from the fact that many will be lost in the weeds during practice, some will also be damaged or nicked in the ejection process. Also some semi-autos are very finicky about reloads (my 1911 Springfield doesn’t cycle them well at all). This, of course doesn’t apply to revolvers. It’s easy to save every case from a revolver. Of course your capacity is limited to 6 or 7,but it is important to learn to be a good shot. My fave is the Ruger GP100 (.357Mag) Go for it! Still, 9mm and .45 auto ammo isn’t THAT expensive yet. Practice, practice practice!
Reloading is lots of fun in itself, and most people are fully capable of doing it. I started when I was 12, as I recall.
