You're Not Ready for That Conversation Yet
How many rounds through a defensive pistol? How many draws from concealment?
Because if you're asking about carry optics before you can consistently execute a smooth draw-to-first-shot from your holster, you've already answered the question wrong. You're shopping for gear instead of earning fundamentals.
A red dot on a carry gun is a *refinement*. It's what comes after you've put enough reps downrange that your draw stroke is automatic, your grip is locked in, and you can actually *find* the dot under stress. Most shooters don't get there in their first year. Some never do.
Right now, a quality holster, a gun that fits your hand, and 5,000 rounds of practice are your priorities. In that order. The optic question is premature. It's also a conversation you can't evaluate yet—you don't know what your real weakness is, and optics mask bad fundamentals instead of fixing them.
Come back when you can draw and fire accurate rounds on demand, day in and day out. When you've actually *worn* your setup in real conditions long enough to know what works. Then we talk glass.
Until then, the best money you can spend is ammo and range time.
