I’m sorta interested in getting one.  I think it would make a good hot weather edc (size and capacity, 21rds).  I’m already in the 5.7 game, with a PS90 & RUGER 5.7 so it fits into the collection without adding a new round.   I’ve never seen in person, let alone held/shot one so any real life feedback based on actual experience is welcomed.

It's an odd round.  Straight wall case, high pressure, blowback.  Factory ammo is typically coated.

This pistol is locked breech short recoil w/ a rotating barrel, IIRC.  The SUB2000 is straight blowback, which is unusual for this round, most of the pistols on the market are lever delayed blowbacks.

Cool!  I did not know that, I thought it was just plain blowback.

Ok, that explains the lube casing need.  Straight wall (true straight wall) swollen by fire pressure is going to want to stick in the chamber if there is a delay.  So a batch of budget cheap ammo (as noted above) not coat3d correctly is going to be a problem in a locked breach system where the pressure is gone before any movement.

@0:21 you can see the upper parts layout for a P90 type receiver, including the barrle return spring.

The barrel does not recoil far, and the barrel return spring is stiff.

ETA: The barrel return spring is modeled in the 3D cutaway video.

It is visible at 1:51 when it changes to the left quartering view.

I liked my PR57, never had an issue with it. I had one of the first to come through my store.

I keep it well lubed, but only shot about 100rds of SS195LF through it.

Then dad mentioned he wanted one, without even knowing I had one, so I gave him mine.

I also have an M&P57, which I thought had low recoil, until I shot the PR57.

Not the MP57 has recoil, but its slide is much heavier and you can definitely feel that mass moving around vs the PR57's comparatively very light slide.

The trigger in the PR57 is pre set DA, like on the Kel Tec P11 or P32; it is a long pull, and had to make the full trip to reset, but it is not heavy at all, and it is smooth.

It's blowback, but there is a spring under the front shroud or muzzle device that allows the barrel to move back about .03-.04". In a sense I usually think straight blow back is a permanently fixed barrel.

I finally got mine out to the range. Low recoil is nice. Seems accurate. Several failures to feed out of a hundred rounds. The biggest problem was that the trigger sometimes didn't reset forward which is not an uncommon complaint with this pistol. Yesterday after I cleaned and lubed it I dry fired it a few hundred times and the trigger problem seemed to finally go away. I'll try it again this week.

Looks like it’s going back to Kel-Tec; I broke it down, cleaned & oiled it and took it out.  Only put 20rds through it, 10 FN and 10 American Eagle ~ 75% failure rate.  With the FN, 5 of 10rds didn’t cycle or extract.  AE none of the 10 would cycle.  I don’t have any AAC, but I figure the results would be the same.  Kinda disappointed so far.

Yeah, that's very disappointing.  They'll make it right, but you shouldn't have to send a gun in right out of the box.

For shits & giggles, I took the MRD (Vortex Defender CCW) off,  only 3 failures in 20rds all failed to cycle with AE ammo.  

15% failure rate is still unacceptable, but I think I know what I'm going to hear back from KT now.

I couldn't resist. Not a ton of rounds yet, maybe 20 of FN blue tip and 25 Hornady Black 40gr V-Max, but no malfunctions. It shoots high-left so it needs a dot. It's so weird I may even carry it. Holy crap does it launch brass!

Interested in hearing how yours works with a red dot.  I haven’t shot mine since I took the red dot off, the failures decreased, but not to the point I’d trust my life with it.  I’m with you, it’s a carry option, but not until I get past the failures, until then it’s just a range toy.

What dot? How much did it weigh?

I ran 54 rounds of Fiocchi 40 grn FMJ through the shop's 57 the other day.  Once you figger out how to get the strippers all the way in there all 10 rounds shoomp right into the mag.  Even loaded the 21st to see the little legs come out.  No oil, out of the box, no jams, just very light recoil for 54 rounds.

Did not notice the false reset when firing live ammo.

Well that's what I ordered too. We'll see if I have any problems.

That'll do. Shot another about 90 rounds today with no malfunctions, which was kind of surprising since this was 50 rounds of American Eagle 40gr FMJ. I've not read the best about it but it worked for me. So far only about 150 rounds in but zero malfunctions.

I've put a Vortex Defender on it since this pic.  I like it a lot!

ETA looks like my pic already has it on there

Put 60rds through mine today, 30 FN & 30 AE, only 1 issue and it was an issue with a round.  I am having an issue with the loading, the first round hangs up so the slide won’t go into battery; probably a loading/user error.   I did take the MRD off, I’ll put it back on and see how it works.  I am liking this little pistol so hopefully I can get it working w/o issues.

I noticed mine hanging up loading the first round a couple of times. Only when running the slide, never when using the slide lock lever. Guess it's a slide release lever.
