I have had a sorted history with my pmr-30. I have always had faith in the design and kel tec as a company.
My pmr-30 was a first generation with a slick grip and fluted barrel. This barrel did keyhole badly with cci and barrel was replaced within a week of buying...+1 on customer service.
Replacement barrel always shot "Paper plate moa" and was never all that spectacular albeit incredibly reliable...More so than my 1911, I might add.
Fast forward 6 yrs... Fredderson claims to have a great new barrel and I jump on it for $45. Accuracy is only nominally better... It's not even worth the $45.
After a broken firing pin, I shipped back to the factory and got a complete upgrade on my pmr.... +1
I now only have armscor 22 wmr ammo for the foreseeable future and it is not recommended... So why not shoot non recommend ammo in a non recommended barrel?
Here are my results.... Original fluted barrel armscor 22 wmr, 10 yrds offhand...

For comparison....

Fredderson on with armscor 10 yrds

Fredderson hornady 30 grn

New factory barrel with armscor
New factory barrel was no better with hornady either.

so the upgrade was the new barrel that kel tec has been using?

My original factory barrel was minute of car door at 15 yards, the federson barrel was minute of doggie door but the threaded KelTec barrel is 2 1/2 inch group at 15 yards with just about all types of ammo I've tried.. Armscorp USA, Hornady 30 grain v-max, Speer Gold Dot, CCI +V, CCI Maxi- Mag. Out of a 25 round mag of mixed ammo at 15 yards, slow fire, off hand, I achieved a 3.5 inch group. I'm pleased with that, now just trying to figure out why the original barrel can't do that....

Ahhh!!! I see. the kel-tec threaded barrel is the most accurate. Funny I have heard or read some where that the threaded barrel also help with ammo function. I don't know why they threaded it as the flash hider they have doesn't look like it would do much to reduce the flash and a silencer would be out of the question.

Jinkster posted about the 5" threaded barrel helping his PMR cycle 30 gr. V-max reliably.

The Buck Rogers looking Kel-Tec threaded muzzle device is more of a blast/flash disrupting cone.

I have seen others say the 5 1/2" barrel was no more accurate than the new unfluted one.
