I wanted a .223 handgun for coyote hunting. Ruled out a Thompson Contender because I wanted a fast follow up shot.
Came to the conclusion that an AR15 based gun was too bulky.
Went with a Kel-Tec PLR-16, which uses an op rod gas system. The gun has a plastic upper and lower receiver, the only plastic gun I own. Barrel length is 9.5". Keep that length in mind when loudness is discussed.
It handles well and balances similar to a large S&W with a long barrel with full underlug.
Recoil is less than a .357 Magnum in an heavy L or N frame, and muzzle lift is about the same. (A compensator is available, but it actually works too good and shoves the barrel lower, requiring the shooter to bring it up.)
Accuracy is good enough to confidently hit a coyote at 100 yards.
Here's the fly in the ointment. I knew it was going to be loud, but underestimated just how loud. It's one of the most obnoxious guns I've ever fired. I think it's a lot worse than a .30 Carbine Blackhawk. Have to wear both quality muffs AND ear plugs. Was planning on wearing electronic muffs, but by themselves they are not enough to protect your hearing. And that's the problem. I need to hear what's going on around me when hunting.
So, unfortunately, it became a range toy. And since it was a range toy, I sent it to an SOT to covert to an AOW, so I could legally put a forward vertical grip on it. If I had converted it, the tax stamp would have been $200. The SOT could do it for $5, though the gun was at his shop for 9 months waiting for the tax stamp to be issued.
The muzzle flash with some ammo is watermelon size. And like I said, the report is incredibly loud. You can feel the muzzle blast concussion against your chest.
Suppressor? Sure. I put my .308 suppressor on it. It reduced the blast to about normal .223 levels, or maybe a bit less to .22 Hornet levels. Got hotter than Hades within only a few rounds. And badly unbalanced the gun. The latter point is something to consider. The weight of the suppressor made it barely tolerable for handling as an AOW, but almost impossible to use as a pistol. My suppressor is all carbon steel. Maybe a titanium .223 rated suppressor might help with balance, but it's still going to be a lot of weight on the muzzle of a handgun for balance.
So, in a nutshell, the points are:
Incredibly loud. The word "painfully" is not out of place.
Badly balances with a suppressor.
Fun range toy.
