"It's (P32) also the only poly frame .32 micro pistol that's on the market"
It also sits in a very rare position among .32 ACP handguns, as one of a few locked breech .23's.
Per my limited memory there are only two others, and they have retarded blowback actions, the Remington 51 in .32 and the Savage 1907 .32, which barely keeps the "retarded blowback" term since it's know that the action is only very slightly, if at all, retarded.
If anyone knows of others I'd love to hear of them, hopefully not plastyguns.
I've carried a P3AT for many years and had only two complaints, (1) the trigger is a steel rod that runs inside the plasticrap trigger and carries the load of finger pressure during firing (Which rod migrated out causing failure to fire, and which I repaired quickly) and (2) the mag release button commonly dropped the mag a fraction of an inch inside my pocket, which I fixed by belt sanding it down flush. I figured being able to fire the six rounds in the mag has priority over changing mags. I found it easy to stick the tip of my thumb on it in such a way that it always releases the mag when needed.
Even though I despise cheap materials in guns I have to admit that Kel-Tec has innovative
engineers, how many "true" handguns (Not rifles claimed to be pistols) carry 30 rounds of .22 Magnum like the PMR-30?
