Question: P365 vs G43X for home defense — what's the practical difference?

Question

My partner and I have been talking about which gun makes sense for us, and these two keep coming up. I know they're both compact 9mms, but I'm trying to understand what actually matters between them for someone like us — we're looking at home defense first, not carrying.

Someone told me the P365 is thinner? Is that a real advantage in a safe or on a nightstand, or is that more for people who carry? And I've heard the Glock holds more rounds — is that a meaningful difference for what we're doing, or does it change how easy the gun is to learn on?

Also, are there reliability or durability differences I should know about? We want to pick one and actually train with it together, so we need something we can both trust and understand.

I'm not sure which direction makes more sense for us. Any thoughts?

Both solid choices, but the practical differences matter for how you'll actually use them.

Thickness: P365 is about 0.9", G43X is roughly 1.1". Honest take — for a nightstand gun or safe, that's not a meaningful advantage. You're not wearing it, so slimness doesn't buy you anything. That feature matters way more if one of you decides to carry later.

Round count: P365 runs 10+1 (or 12+1 with the flush mag), G43X is 10+1 standard. In home defense distance and scenario, that's splitting hairs. The real question is which trigger and ergonomics let you both shoot it accurately under stress — that's where your training dollars go.

Reliability: Both are genuinely solid. P365 had some early striker issues years ago, but Sig addressed that. G43X is Glock-platform, which means parts commonality if you ever expand your training ecosystem. Neither one is the weak link in a home defense setup.

What I'd actually focus on: Can you both *reach* and *manipulate* the controls the same way? P365 has a shorter trigger reach; G43X has a wider grip. If one of you has smaller hands, that changes the recommendation. Take both to a rental range if you can, not just a sales counter.

Which way are you leaning so far, and does one of you have hand size differences I should know about?

Southpaw nailed the reliability and ergonomics piece. I'll add what matters for actually securing and deploying these guns at home.

Holster ecosystem is where this decision gets real teeth:

**P365 wins on aftermarket depth.** Tier-1 Concealed, JM Custom Kydex, Werktat, Phlster — all make dedicated rigs. If you want a proper bedside holster with a full trigger guard and retention, P365 options are everywhere. For a nightstand gun, that matters because you need something that keeps the gun oriented and secure but deploys fast without fumbling.

**G43X has solid options, but fewer.** Glock's smaller compact footprint means fewer purpose-built home defense rigs compared to the P365's market saturation. You can find good ones (Tier-1 makes a G43X bedside, for instance), but you're comparing a deep bench to a shorter one.

Where G43X wins: If you ever cross-train with other Glocks or decide to carry later, holster swap is trivial. One trigger guard, one mounting system. P365 accessories don't transfer to a full-size Sig.

For home defense specifically — gun in a safe or bedside — I'd lean P365 just because you get more vendor options and can dial in exactly what "secure but deployable" means to you without settling for second-choice rigs.

What's your storage plan looking like? That shapes the holster recommendation more than the gun choice does.

Thank you both—this is exactly the kind of detail we needed to actually think this through as a household decision.

Southpaw, I appreciate you drilling down on the ergonomics piece. That's something my partner and I haven't tested yet, and honestly it's the part that makes me nervous. We both need to be able to operate whatever we choose, and "feels different in hand" is real even if it sounds small. I'm wondering if you'd recommend we rent both at the same range and spend time with each one, or is that overkill for a home defense setup?

Holster_notes, your point about the P365 having more bedside-specific options is reassuring. I've been worried about getting this to "safe but actually accessible" without it becoming a fumbling situation in the dark. The idea that we have more vendor choices to find something that actually fits our nightstand layout makes sense.

One thing I want to make sure I'm asking right: we're thinking a biometric safe on the nightstand, not just a holstered gun sitting out. Does that change any of this? I'm also curious whether the trigger reach difference southpaw mentioned actually matters once a gun is in your hand from a rested position—is that more of a carry thing, or does it matter for home defense too?

I know I'm asking a lot of clarifying questions, but we want to pick one and actually train together, so getting this right before we commit matters to us.
