Kel-Tec P17 Review: A Light, Threaded 16+1 .22 Pistol

The P17 is a light polymer .22 built to be inexpensive to own and easy to modify. That mix is its appeal, and the reason to inspect and test any example before you trust it.

Short answer

The Kel-Tec P17 is a lightweight 16+1 .22 LR pistol with a threaded barrel and an optics-ready version. It suits plinking, practice and suppressor use if you feed it high-velocity ammunition and test it properly; it is not a precision target pistol.

Where the P17 sits in the .22 pistol world

There are three broad ways to buy a rimfire pistol. You can spend for accuracy, as with a bull-barrel target gun. You can spend for capacity and attitude, as with an oversized plinker. Or you can buy something light, simple and straightforward that you can modify as you go. The Kel-Tec P17 belongs to the third group.

It is a polymer-framed semi-auto with a listed capacity of 16+1, a short barrel with a threaded variant, and an optics-ready version for a red dot. It is meant to be a gun you actually carry to the range in a small bag, not one you baby.

This is a buyer's review built from the listings and general rimfire reasoning. We have not fired this pistol, and quality varies from gun to gun in any budget-oriented design. The advice below shows how to check an example yourself.

The two versions in plain terms

	OD green model	Black optics-ready model
Caliber	.22 LR	.22 LR
Capacity	16+1	16+1
Barrel	Listing notes a threaded variant	Check the listing
Optic mounting	Check the listing	Sold as optics-ready
Extras	Listed with the pistol	Listed with three magazines

The first is the Kel-Tec P17 in OD green; the second is the P17 optics-ready black model. If you are certain you will add a red dot, the optics-ready version saves you a gunsmithing step. If you are not, the standard model is simpler to live with. If you are buying with a suppressor in mind, confirm that the specific listing you are looking at is the threaded configuration, because the listings differ.

What the P17 gets right

It is light. That is the design's whole identity. A pistol that does not weigh much is easy to carry to the range and easy for smaller hands to manage.

It has real capacity. Sixteen rounds plus one in the chamber is more than most conventional .22 pistols hold, and a spare magazine extends a session considerably.

It is a good platform to learn on. A simple blowback action is straightforward to field-strip and understand. That matters to a shooter who wants to learn how a semi-auto works, though beginners should plan for the troubleshooting that goes with it.

It accepts a suppressor and an optic. Both variants are aimed at the modern shooter who wants those options. Rimfire thread pitch is commonly 1/2x28, but confirm the pitch for your specific barrel; SuppressorReady's thread pitch cheat sheet is a starting point.

What to watch

Ammunition sensitivity. Light slide, short barrel: this is the combination that most depends on cartridge energy. High-velocity copper-plated ammunition is the standard recommendation, and standard-velocity target loads are the common source of stoppages. Our ammo guide for rimfire pistols explains why and provides a test method.

Magazine condition. In any .22 pistol the magazine causes a large share of problems. Number your magazines and retire any that cause repeated stoppages. The jam troubleshooting guide explains the diagnosis.

Fit and finish. A pistol positioned for value tends to have more variation between examples than a premium one. That is not a reason to avoid it; it is a reason to inspect it.

Inspecting a new example

We do not have verified information on quality-control rates for this pistol, and we will not pretend to. What we can offer is a practical checklist for a new .22 pistol of any brand:

Function check, unloaded. With the muzzle in a safe direction and the chamber verified empty, cycle the slide, work the trigger, and confirm the safety and slide lock behave as the manual describes.
Check the optic or sight fit. If you bought the optics-ready model, test-fit before you commit to mounting.
Read the manual and the warranty terms on Kel-Tec's own site, including how to start a service request.
Break it in with high-velocity plated ammunition. Run several magazines across at least two different loads and note each stoppage.
Keep a log. If the pattern points at the gun rather than ammunition or a magazine, contact the manufacturer promptly rather than modifying anything yourself.

That is the same advice that applies to any new semi-auto, and it will tell you more than any generalization we could offer.

The optics-ready question

An optics-ready model saves you from having to find a way to fit a red dot, but it does not choose the red dot for you. Before you buy an optic, find out from Kel-Tec which mounting pattern or plate the pistol uses, and match it to the footprint of the dot. Our network sibling GunOptics explains the common footprints and their trade-offs.

A red dot on a light .22 pistol is also a good teaching tool: it shows you every movement of the muzzle during the trigger press. Test the iron sights first if the pistol has them, so you know what the gun does without help.

Ammunition that makes sense to try

Start with high-velocity copper-plated loads of the kind covered in our Aguila Super Extra lineup comparison and the Browning BPR guide. Both are the standard category for blowback pistols. Avoid judging the gun on a first outing with a different class of ammunition such as subsonic or very light primer-only loads.

If you plan to run it suppressed, test a subsonic load before relying on it, because a light pistol with a suppressor and low-energy ammunition is the combination most likely to short-cycle. Suppressed shooting also fouls faster; see rimfire suppressor fouling.

Versus the alternatives

Ruger Mark IV Target: more accurate, more mass, easier to shoot well, and less of a grab-and-go gun. It suits bullseye or careful practice. See Mark IV for bullseye.
Kel-Tec CP33: more capacity and a longer sight radius, with a more demanding magazine. See our CP33 review.
Others: best .22 pistols by role sorts the field by purpose.

Pick it if

You want a light, simple, modifiable .22 pistol for casual shooting.
You plan to add a red dot or a suppressor.
You are willing to test ammunition and magazines and do the basic maintenance.

Skip it if you want benchrest-style accuracy, a forgiving first handgun, or a pistol you can put away and trust without testing.

Frequently asked questions

How many rounds does the Kel-Tec P17 hold?

The listings show 16+1: sixteen in the magazine and one in the chamber. The optics-ready listing also notes that it ships with extra magazines, so check the current listing for what is included.

Does the P17 have a threaded barrel?

The listing for the OD green model notes a threaded variant is available. Confirm the thread pitch and whether your exact model has the threaded barrel before buying a suppressor or adapter.

What ammunition does the P17 prefer?

As a light blowback pistol with a short barrel, it generally does best on high-velocity copper-plated ammunition. Test a couple of loads, since individual guns vary.

Is the P17 good for beginners?

It is simple to operate, but light pistols need ammunition and magazines to be right, so troubleshooting can frustrate a new shooter. A heavier pistol is often more forgiving.
