The question behind the question
When someone asks "should my carry gun have a safety?" they usually mean something more specific: should my striker-fired pistol have a thumb lever that blocks the trigger, or not?
Modern striker guns without a manual safety still have internal safeties: a trigger blade, a firing-pin block, a drop safety. Those are passive. They work without you doing anything, and they don't stop the gun from firing if something presses the trigger. A manual safety is active. You switch it on and off.
That's the whole debate in two sentences. One side says an active block is worth having. The other says an active control is one more thing to get wrong under stress. Both sides have a point. If you've already decided you want a lever and just need models, our best carry pistols with a manual safety list is the shopping guide. This piece is about the decision itself.
Side by side
| Manual thumb safety | No manual safety | |
|---|---|---|
| Holstering | Lever blocks the trigger while the gun goes in | Relies on clear holster mouth and finger off the trigger |
| Drawing | Thumb must sweep the lever off every time | Nothing extra to do |
| Training load | Higher: off on the draw, on before holstering | Lower: one less step to ingrain |
| Stress failure mode | Forgetting to disengage it | Something entering the trigger guard |
| Best fit | Appendix carriers, people who value the extra block, 1911-trained shooters | People who want the simplest manual of arms and will train holstering carefully |
| Holster fit | May need a holster cut for the safety | Wider holster choice |
The case for a thumb safety
Holstering is the risky moment. In everyday carry, the gun sits in a holster and does nothing. Most of the risk is concentrated in the few seconds when it goes in or comes out. Things that can get into a trigger guard while holstering include a shirttail, a jacket drawstring, a seatbelt or a finger that didn't come off the trigger.
Appendix carry makes that moment more serious. With appendix inside-the-waistband carry, the muzzle points toward your groin and leg as the gun goes in. Our holster position guide covers the slow, deliberate holstering habits AIWB demands. A thumb safety adds a mechanical block during exactly that moment. That's the strongest argument for a lever, and it's why many appendix carriers choose one.
It can give you a second chance in a struggle. Some carriers like that a gun grabbed by someone else may not fire right away if the safety is on. That's a real but limited benefit; anyone who knows guns will find the lever.
It matches what some people already know. Shooters raised on 1911s or with law enforcement or military training on safety-equipped guns often find a lever natural. Their thumb already does the work.
The case against
It must be trained, every rep. A safety only helps if you take it off every time you need to shoot and put it back on every time before you holster. That has to be built into your draw. If you practice sometimes with a lever and sometimes without, you build two conflicting habits.
Forgetting is the main failure. The classic manual-safety failure under stress is a click instead of a bang because the lever is still on. Training reduces that, but it doesn't eliminate it for someone who doesn't practice.
It isn't a substitute for a holster. A lever can be bumped off by keys in a pocket, a purse's contents or a car door. A gun with a safety still needs a rigid holster that fully covers the trigger guard. If you're counting on the lever instead of a good holster, you've made the gun less safe, not more.
Small levers on small guns. On micro-compacts the lever is small by design so it won't snag. That's good for concealment but means you should handle the gun before buying to confirm you can work it reliably, especially with cold hands or a less-than-perfect grip. Left-handed shooters should check whether the safety is ambidextrous.
Popular carry guns sold both ways
The good news is that you often don't have to change guns to change your answer. Several of the most popular carry pistols are sold with and without a safety.
Smith & Wesson M&P9 Shield Plus
The Shield Plus is sold in thumb-safety (TS) and no-thumb-safety versions. Ammunition Depot lists, for example, the Shield Plus 3.1-inch optic-ready with thumb safety (S&W model 13536), described as "striker fire action with thumb safety." Check the model number on whichever version you buy, since product listings sometimes leave the safety out of the description. Our Shield Plus buyer's guide walks through the variants.
Sig Sauer P365 family
Sig sells manual-safety versions of several P365 models; the listings we checked carry "MS" in the model number. Ammunition Depot lists the P365-XMACRO 3.7-inch 17+1 (365XCA9BXR3MS) with a "Manual Thumb" safety in its spec table, and a P365 3.1-inch 10+1 whose description says it "features a manual safety." Other P365 models are sold without a lever, so read the spec line, not just the name.
Springfield Hellcat
Springfield announced the Hellcat OSP with a manual ambidextrous safety on February 25, 2021 (model HC9319BOSPMS). Its press release describes a low-profile thumb safety on both sides of the frame, contoured to avoid snagging, with the Hellcat's passive safeties kept in place. Standard Hellcats, like the Hellcat 3-inch OSP listed at Ammunition Depot, don't mention a lever, so confirm the exact model if you want one.
Ruger LCP MAX
Ruger's LCP MAX page lists several variants with a manual safety, including a California-approved model. That's useful if you want a .380 pocket gun with a lever.
Glock
Glock's commercial pistols use its Safe Action system and are sold without a manual thumb safety. If you love the Glock layout and want a lever, you'll need a different brand. Aftermarket safeties exist, but we don't recommend modifying the fire control of a carry gun; buy one that ships with the feature.
Which carry position favors which
- Appendix (AIWB): The strongest case for a thumb safety, because of muzzle direction during holstering. If you go without, holster slowly every time and keep the holster mouth clear.
- Strong-side hip: The holstering argument is weaker, since the muzzle points down and away. Choose based on your training habits and other guns you own.
- Pocket: Don't count on a lever. Keys and coins can move it. Use a pocket holster that fully covers the trigger guard and keep the pocket empty of anything else. See our pocket carry guide.
- Off-body (bag or purse): Same as pocket. The holster or dedicated compartment does the safety work.
If you choose the lever, train it
- Make it part of the draw. Your thumb sweeps the safety off as the gun comes up toward the target, not as a separate step after.
- Re-engage before holstering. Safety on, finger out of the guard, look the gun into the holster, holster slowly.
- Dry-fire it every session. With the gun verified unloaded and all live ammunition out of the room, practice the draw and the safety together. Our ten-minute dry-fire plan works with a safety; just add the sweep to every rep.
- Keep all your guns consistent if you can. If your carry gun has a lever, a home or range gun with the same manual of arms helps.
If you choose no lever, the training is still there. It just moves to holstering discipline: slow, deliberate, eyes on the holster, clothing cleared out of the way.
Either way, buy a holster made for your exact model and configuration. Some are cut to leave room for the safety. Ammunition Depot's holster section can be filtered by type.

Frequently asked questions
Is a manual safety safer on a carry gun?
It adds a mechanical block that can help during holstering, especially in appendix carry. It is only safer if you train it consistently, and it never replaces a rigid holster that covers the trigger guard.
Do Glocks have a manual safety?
Glock commercial pistols use the Safe Action system and are sold without a manual thumb safety.
Does the Sig P365 have a manual safety?
Some versions do. Sig sells manual-safety P365 models, usually marked MS in the model number, alongside models without one. Check the exact model spec before buying.
Can I get a Shield Plus with a thumb safety?
Yes. The M&P9 Shield Plus is sold in thumb-safety and no-thumb-safety versions. Confirm the model number and the listing's description.
Should I get a manual safety for appendix carry?
Many appendix carriers choose one because the muzzle points toward the body during holstering. If you skip it, holster slowly every time with a rigid holster and clothing cleared away.
