Full-Size vs Compact Nightstand Pistol: Does Size Matter at Home?

Why size is even a question

Our nightstand pistol setup post covers the light, the storage and the routine. This one tackles the question that comes before it: should the gun next to your bed be the big one or the small one?

For carry, the answer usually tilts compact. Shorter slides and grips hide better, and a pistol you leave at home because it's uncomfortable does you no good. At home, none of that applies. The gun sits in a quick-access safe. It doesn't have to hide under a shirt or ride on a belt all day. So the advantages of a bigger gun come at almost no cost.

The decision really comes down to two things: how much the full-size advantages matter to you, and whether you want one gun that does both jobs.

Head to head

Specs above come from Ammunition Depot's product listings and Wikipedia's Glock entry. The gaps are small. A Glock 19's barrel, per Wikipedia, is about 12 mm shorter than a Glock 17's, and the magazine holds two fewer rounds. That's the scale of difference we're talking about.

Sight radius and shootability

Sight radius is the distance between the front and rear sights. A longer radius makes small alignment errors smaller on target. With iron sights, a full-size gun is a little more forgiving, especially when you're tired, scared and shooting in poor light.

A full-size gun also weighs more, and more weight soaks up recoil. Ammunition Depot lists the Glock 17 Gen5 at 33.3 ounces. That extra heft is a nuisance on a belt and a quiet help in your hands.

Two things shrink this advantage. If your pistol wears a red dot, sight radius stops mattering, since the dot doesn't depend on aligning two sights. And at bedroom and hallway distances, the difference in practical accuracy between a 4-inch and 4.5-inch barrel is small for most shooters. Grip and trigger control matter far more.

Capacity

Two or three rounds is the full-size advantage with these examples. Whether that matters is a reasonable debate. Most home-defense incidents are not long gunfights, but nobody plans on needing the 16th round and then regrets having it.

Two practical notes. First, capacity depends on the magazines you buy. Ammunition Depot's Glock 17 Gen5 listing (PA175S201) is a 10-round version sold for states with magazine limits, while standard Glock 17 magazines hold 17. Check your state's rules before buying either. Second, a spare magazine near the nightstand closes much of the gap; see our nightstand spare mags post.

Lights and accessories

A weapon light is non-negotiable on a home-defense handgun. You must identify what you're pointing at. Our weapon light post makes that case in full.

Full-size pistols have a longer dust cover, the frame section where the light clamps. That gives room for full-size lights like the Streamlight TLR-1 HL, which Ammunition Depot lists at 1,000 lumens on a CR123A cell with a clamp for Glock-style and Picatinny rails.

Compacts can take most full-size lights too, but the light may stick out past the muzzle, and it can affect holster fit if you carry the gun. That's why compact-specific lights exist. The Streamlight TLR-7 HL-X USB, per its listing, makes 1,000 lumens on the rechargeable SL-B9 battery or 500 on a CR123A. The smaller TLR-7 X Sub is listed at 500 lumens for subcompacts like the P365 XMACRO.

For a dedicated house gun, the full-size light on a full-size gun is the simple answer: big switch, big battery, no compromise.

The one-gun argument

Here's the strongest case for the compact. If you carry a Glock 19 every day, you've practiced its trigger, grip, reload and holster draw hundreds of times. Under stress, people fall back on what they've practiced. Making the nightstand gun the same model, or literally the same gun, means one manual of arms and one set of habits.

It also simplifies logistics: one magazine type, one holster, one light, one load. Our HST 124 nightstand post covers running the same ammo for carry and home.

The trade-offs are worth naming. If the carry gun comes off your belt and goes into the bedside safe each night, the move from holster to safe needs to be careful and routine. And if one gun does both jobs, the house is unarmed while you're out. That may be fine for your household. Just decide it deliberately.

A middle path many owners choose: carry the compact, and keep a full-size version of the same family at home, like a Glock 19 and a 17, or a PDP Compact and PDP Full Size. Same controls, same trigger, slightly different size.

Example pairings

Glock 17 and Glock 19

The default pairing. Wikipedia notes the Glock 17 entered service with Austria's military and police in 1982, and the Glock 19 followed in 1988.

• Glock 19 Gen5, 4.02-inch, 15+1 for carry and home.
• Glock 17 Gen5, 4.49-inch (the listed version ships with 10-round magazines).

Walther PDP Full Size and PDP Compact

Walther's PDP line is optics-ready from the factory, which takes the sight-radius question off the table if you add a dot. Ammunition Depot lists the PDP Full Size at 4.5 inches and 18+1, and the PDP Compact at 4 inches and 15+1.

• Walther PDP Full Size 4.5-inch, 18+1.
• Walther PDP Compact 4-inch, 15+1. Our PDP Compact review has more.

Lights to match

• Streamlight TLR-1 HL, 1,000 lumens, for full-size frames.
• Streamlight TLR-7 HL-X USB, a compact light that keeps the muzzle clear on shorter guns.

How to decide

1. Do you carry? If yes, and you'll only buy one gun, choose the compact you carry well. If no, choose full-size.
2. Who else might use it? If a partner with smaller hands will use it, have them try both. A full-size grip is not always easier for smaller hands; fit beats size.
3. Light first. Pick the light, then make sure the gun takes it and you can reach the switch with your normal grip.
4. Storage second. Make sure your quick-access safe fits the gun with the light attached. Many bedside safes are sized for compacts.
5. Practice third. Whatever you choose, shoot it enough to be boring.

The bottom line

For a gun that only lives at home, full-size wins on the margins: a bit more capacity, sight radius, weight and light room, at no real cost. If you carry, the compact you already know is a perfectly good nightstand gun, and one manual of arms has real value. Either way, a weapon light, a quick-access safe and practice matter more than half an inch of slide. Compare more options on our best home-defense pistols page.
